Windows users are not happy.

[luisrudge]

It all started with this conversation.

As I said, I'm pretty much a newbie and I don't even know what node-gyp does, but what I DO know is that it's a pain to run Windows and install a project with node-gyp as a dependency.
Some numbers:

• 403 questions on stackoverflow (node-gyp windows)
• 224 issues mentioning "windows"

It's bizarre that a nodejs developer needs to install visual studio (even the express edition) in order to be able to work on Windows. Even more bizarre is that I, as a .NET developer with full visual studio installed in my machine still can't download a bunch of projects that use this project.

With that being said, I'd like to know from all of you what should we do to make windows users fall in the pit of success? What are the alternatives? Does Microsoft can solve this in any way?

This issue is fixed (kinda)

@mousetraps pointed that Microsoft is shipping the C++ build tools separately now. Check here

Some updates on this gigantic thread

Absolutely non-official statement that @microsoft is aware of this issue and seeing what can be done

@mousetraps said that this thread "is high on people's radar" at @microsoft

Very good Q&A about noge-gyp issues on Windows and why they happen

@dekarguy took the time to answer some questions about what we all are going through

[johanalkstal]

Is there some common effort we can do?

The reliance on both Visual Studio (or the Windows SDK) and Python is such a pain. And when it still doesn't work 99.9/100 times anyway, while node-gyp still being so heavily used by the Node community, it's enough to make a grown man cry or give up on using whatever it was that relied on node-gyp.

[daanl]

+1 this a world of pain, took me hours to install a project with node_gyp

[joeeames]

+1 after 8+ hours of trying, still can't use anything that relies on node-gyp.

[GradyD]

👍 after multiple days trying to get this to install I am still fighting VS errors!! It just never gives up.

Atwood's Law: any application that can be written in JavaScript, will eventually be written in JavaScript.

[luisrudge]

@TooTallNate any thoughts?

[TooTallNate]

node-gyp v2.0.0 (just released) has an updated gyp version that adds support for MSVS 2015, and should hopefully ease of lot of this pain for Windows users.

[TooTallNate]

Additionally, you guys should probably support my current effort in bringing FFI into node core, thus eliminating node-gyp from the equation for the majority of use-cases.

[luisrudge]

Awesome @TooTallNate. I don't have the skills to understand and support your argument, but I can give you a 👍 haha :(

Congratz on the new release, but I believe we have to wait for everyone to update the dependency version and that maybe never happens.

[b-long]

I'm also struggling with this quite a bit. I'm trying to follow along with this guide (https://github.com/TooTallNate/node-gyp/wiki/Visual-Studio-2010-Setup), but I'm not having much luck.

The guide in the wiki directs us to http://www.microsoft.com/visualstudio/eng/downloads#d-2010-express, which redirects to https://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express and that page does not offer VS 2010 for download (it's exclusively 2013).

Even more hilarious / sad, in attempting the uninstall procedures, I somehow wound up with "Microsoft Visual Studio 2010 Service Pack 1" listed in my Programs and Features (Uninstall menu), but when I click "Uninstall/Change", I'm given an error after a while that says "A compatible version of Visual Studio 2010 was not detected on the system. This update is designed for only the Microsoft Visual Studio 2010."

[luisrudge]

Yeah. There needs to be a better way

[b-long]

@TooTallNate I'm pretty sure you're doing the best work there is for Node support on Windows 👍 :) Could I make a request that we update the wiki page (or add a new wiki page) describing the steps for VS 2015 ?

[luisrudge]

FYI: npm i c3 still fails. Even with vs2015 installed. @TooTallNate any ideas?

I just found out about the environment variable (GYP_MSVS_VERSION ) option here: #339 (comment) , it might help @luisrudge or others. Any other updated happy paths for Windows users? /cc @TooTallNate @isaacs

[srlowe]

+1 This is a real pain point - I'm spending as much time fiddling around with VS and node-gyp as I am coding at the moment. IMO the core of the problem is all these MS/VS dependencies, which are a total mess - is there any way we could circumvent these?

[aahoo]

I installed socket.io with MSVS version set and then installed the rest of the stuff:

npm install socket.io --msvs_version=2015

I hope this helps if not you can look @ socket.io / issues.

The root of this issue is that Microsoft's willingness to provide a c/c++ compiler on Windows is lackluster. Right? Is there not some other approach (e.g. using a Cygwin DLL or something from MinGW ) that might suffice?

[aahoo]

@Sogl
I didn't follow from the beginning. Take a look at Updating npm's bundled node gyp if you already haven't.

[thoroc]

Other solution would be to settle a non MSFT compiler and use one that is still available for the plateform.

[Sogl]

@Baazoo

Didn't help.

@thoroc

Also found info about build with pangyp:

npm i pangyp -g
npm config set node-gyp pangyp

Also this tool works with io.js.
For me it doesn't work because my userprofile name in Russian.
But it still use MS compiler...

[thoroc]

Well I am resorting to install a VM with Ubuntu on it for dev. But I am not really happy to have to change OS just because node-gyp is forcing me into installing MSFT dev tooling. From I have read changing to an FOSS C++ compiler would mean a major refactoring of the tool itself. Which incidently and understandly, no one wants to undertake.

[aahoo]

@Sogl
I just encounterd similar issue when trying to install gulp-devtools.

c:\users\hamed\.node-gyp\0.12.7\deps\uv\include\uv-win.h(32): fatal error C1083

amed\AppData\Roaming\npm\node_modules\gulp-devtools\node_modules\socket.io\node
_modules\socket.io-client\node_modules\ws\build\validation.vcxproj]

This is what worked for me:

1. Switched terminal from Powershell to CMD (Powershell didn't work)
2. set GYP_MSVS_VERSION=2015
3. Installed the package in my case npm install -g gulp-devtools

There is one more suggestion!

[Sogl]

@Baazoo
Just tried things you describe.
Same 'v8.h' error =(

One last step that I want to try - install VS 2015 😆

[b-long]

I also resorted to the workflow @thoroc described (using a VM inside Windows).

[Sogl]

@thoroc
@b-long

Yep, guys. This problem also has led me to use Vagrant (with VirtualBox) and Scotch Box.

[luisrudge]

Sorry. The solution can't be "use a vm instead"

[galeksandrp]

@jasonwilliams200OK, yes, but file from patch you referred is .gypi file, when gyp is written in python. And look, there are references to DirectX SDK in it (which obviously not needed to be used in crossplatform buildsystem.

[ghost]

there are references to DirectX SDK in it

@galeksandrp, the patch I linked is highlighting the portion of gypi fix which anyone can apply locally. You missed the point, which was this particular issue (among dozens of others discussed in this thread) can be fixed in gyp.

To your meticulous concern, in node-gyp crossplatform buildsystem scenario, modify ~\.node-gyp\<version>\include\node\common.gypi or node_modules\node-gyp\addon.gypi file to add these dirs (suiting your drive letter and exact version of latest available SDK):

'include_dirs': [
  'C:/Program Files (x86)/Windows Kits/10/Include/10.0.10586.0/um',
  'C:/Program Files (x86)/Windows Kits/10/Include/10.0.10586.0/shared',
  'C:/Program Files (x86)/Windows Kits/10/Include/10.0.10586.0/ucrt',
  'C:/Program Files (x86)/Windows Kits/10/Include/10.0.10586.0/winrt'
],

This will make the node.js package with C++ add-on compile with Windows 10 SDK, without having to install Windows 8 SDK.

[ericgrosse]

For those still having node-gyp issues, please try the following:

Step 1

Make sure you have the latest version of Node. Right now it is v5.11.0 Stable and includes an up-to-date version of npm. Even if you apply legitimate fixes found in this thread, you will still get node-gyp errors using an outdated version of Node or npm.

Step 2

Use Mousetrap's solution, found here. You don't even need to read her full post, just blindly follow steps 1-4 that she provides.

Step 2

If you're getting an error ImportError: No module named gyp, it means you need to reconfigure how npm accesses the python shell. The instructions are given here.

---

I have tried this setup on three different OSes (Windows 7, Windows 8.1, Windows 10) and it always works. You don't need Visual Studio, just the Visual C++ Build Tools 2015.

As an additional note: I always run npm install from a git bash terminal that's run as administrator.

[fskreuz]

Confirming that @mousetraps method still works as of the time of writing with no additional steps.

OS: Microsoft Windows 10 Pro N (Build 10586)
Node: 5.11.0
npm: 3.8.6

Notes:

• Git Bash isn't required to run as administrator.
• No Visual Studio required.
• No Windows SDK required.
• Install the Visual C++ Build Tools 2015 Technical Preview, not Visual C++ Build Tools 2015.
  • If you installed it without having to select "Custom", you probably got the wrong one installed.
  • If you encounter an error containing MSB4019, you probably got the wrong one installed.
• No environment variables required.
  • You only need npm config set msvs_version 2015 --global
  • If you set GYP_MSVS_VERSION, you can unset that.
  • If you did some env var or regedit hacking like this, you probably need to undo those.

[barocsi]

According to @fskreuz if you had this set during your struggle, make sure its updated to the most recent version
SET VCTargetsPath=C:\Program Files (x86)\MSBUILD\Microsoft.Cpp\v4.0\V120
for me its v140

[am11]

@barocsi, note that if you have latest msbuild in PATH, then you do not need to set VCTargetsPath:

SET PATH=C:\Program Files (x86)\MSBUILD\14.0\Bin;%PATH%

In fact, you should rather unset it if it is set as process, user or machine env variable; because if you have multiple VS versions installed, fixing this environment variable to a version will led to other kinds of build errors. VCTargetsPath is usually set in vcxproj explicitly or via the MSBuild default .targets.

[barocsi]

Then it might have only worked for my particular bad chain of setups. Will clean up again, thanks.

[Ucodia]

Where did @mousetraps comment go? It contained the full step by step guide but it looks like it has been deleted.

Edit: My bad, a low connectivity prevented my browser from showing the comment as @jasonwilliams200OK mentioned.

[ghost]

@Ucodia, that comment is still there. The page size is crazy long though, probably that's why browser must be acting funny. I vouch to open a part two of this issue for persistently unhappy users. 😄

[frankred]

Having done the following steps still does not work:

1. Installing Windows10
2. Installing node v.4.4.3 (LTS)
3. Updating npm to 3.8.8
4. Installed python 2.7.11 and added to path
5. Installing "VC++ Build Tools Technical Preview" https://www.microsoft.com/en-us/download/confirmation.aspx?id=49983
6. npm install node-expat@2.3.13

So, do we still need to download and install the entire Visual Studio package just to install a couple native node modules that require node-gyp? Seems kind of excessive to me, the VS package is insanely large, takes a bit to install and also installs tons of MYSQL useless packages that you need to uninstall AFTER. Please tell me there is a solution to this. (Obviously, running it on Linux it only needs gcc and some other deps, which is fine) -- but I dev on Windows :(

Also, where the fuck is Ryan Dahl? He should be working on node still. Where did he go?

Edit2: Also why hasn't Github implemented pagination on issue pages? What a mess.

[luisrudge]

@Dillybob92 no. You just need to download the msbuild tools: #629 (comment)

[luisrudge]

@Dillybob92 BTW, your tone doesn't help anyone.

[ghost]

@luisrudge My tone? This has been a problem for years and for Ryan Dahl to leave node and leave a mess for the community is a disgrace.

Also, mousetraps post is not really a solution. That's still around 8 Gigabytes of SDK's. I'd rather just install VS 2013 express.. Also, those SDK's installers don't offer a custom installation folder. This is still a major issue that no one seems to address so my tone will stay the same.

[luisrudge]

@Dillybob92 I understand it's not ideal, but it is what it is.
It's not 8GB, it's less than 800mb for just the build tools. You don't need the full SDK.

One more note on this thread: the Visual C++ Build Tools are located here: http://landinghub.visualstudio.com/visual-cpp-build-tools

[am11]

@AndrewPardoe thanks for sharing the link.

On that same page, it is mentioned that there is also a NuGet feed available for VC++ latest build tools, which we can incorporate in our node.js build process for targets where there C++ compiler is missing, using nuget.exe (the executable is wget'able from here).
For example, in PowerShell:

# download nuget
wget https://dist.nuget.org/win-x86-commandline/latest/nuget.exe -OutFile nuget.exe

# install VC build tools
./nuget install VisualCppTools -source http://vcppdogfooding.azurewebsites.net/nuget/ -Prerelease

Although this is one huge download, but still might come handy for someone to unblock their users from not getting the npm packages installed at all, and automate the build process for them.

Success installing npm bcrypt module on windows 10

• nodejs version: 4.4.5
• npm version: 2.15.5
• bcrypt version 0.8.7

System 1 (desktop)
Windows 10 - Pro - 64 bits - FRENCH
Intel Core i7-3770 CPU @ 3.40GHz
16 GB RAM

System 2 (laptop)
Dell XPS 15 9550
Windows 10 - Family - 64 bits - FRENCH
Intel Core i7-6700HQ CPU @ 2.60GHz
16 GB RAM

---

The steps I will detail here, as well as the output, are those from system 1 (but the steps were the same on system 2).
I am not claiming any of these steps are the correct ones, but they do reflect the sequence that led to a successful install of the bcrypt npm module (version 0.8.7, as of june 10, 2016).

STEP 1
Perform full installation of C++ Build Tools 2015 (from: https://blogs.msdn.microsoft.com/vcblog/2016/03/31/announcing-the-official-release-of-the-visual-c-build-tools-2015/)
(I say full install because this is what I did, however I don't claim that the full install is necessary)
Note: this may take a while as the full program is over 4GB

STEP 2
Install Python 2.7.11 (from: https://www.python.org/)
Note: during installation select the "add to PATH" option (which is not selected by default)

STEP 3
Run:
npm config set msvs_version 2015 --global
Note: I ran it as administrator in Windows cmd.exe

STEP 4
In my NodeJS project folder (a little blog app i am writing to learn NodeJS), I then ran the install command:
npm install bcrypt --save

This is the output I got (********** asterisks are simply used to hide my local project folder path):

npm WARN package.json blog@1.0.0 No repository field.
npm WARN package.json blog@1.0.0 No README data

I am now able to run bcrypt() commands in my NodeJS app, they turn out something like:

$2a$10$pDJX6lz6QBVatYCC.KiOJ.q6t6uAlKxRsny9tEPiSHTMhNBIhymW2

I have no way of knowing if these hashes are perfect bcrypt hashes be they look good to me.

I would appreciate any input regarding the importance of the warnings referenced in the output above.

Thanks to all who contributed to this thread :)

This issue was addressed with the release of the VC++ Build Tools, and an updated list of instructions for Windows developers both in the node-gyp README and in the new https://github.com/Microsoft/nodejs-guidelines repo.

For any further problems, bug reports, suggestions, etc. related to installing/compiling native modules, please open a new issue in this repo, or at https://github.com/nodejs/node, or - if the issue is pertinent to a specific module and not to node/nodegyp in general - in the module's own issue tracker. I believe those avenues will be more productive than continuing to comment on this giant thread, so I am locking it now.

Thanks again to everybody who contributed to the discussion and resolution! 😄
