mobile-spec project creation fails with error "Cannot find module 'cordova-common'" #159

gandhirajan · 2018-11-27T09:39:01Z

mobile-spec project creation fails with the error "Error: Cannot find module 'cordova-common'" when trying to execute the command - "node ./cordova-mobile-spec/createmobilespec/createmobilespec.js --android --forceplugins"

If I try adding cordova-common module in mobile-spec project manually and try executing the platform add command using - "root_folder\cordova-cli\bin\cordova.cmd platform add "root_folder\cordova-android" --verbose" , platform addition is successfully.

Not sure how to bring in cordova-common module installed as dependency while creating mobile-spec project

How did you setup your Cordova folders with all the checkouts before running this command?
What does "try addinv cordova-common mobile in mobile-spec project manually" mean?

gandhirajan · 2018-11-27T16:58:31Z

@janpio I just checked out all the repos to a root folder using coho repo update. In the mobile-spec project, I did 'npm install cordova-common'

janpio · 2018-11-27T17:31:38Z

Please install a new node version (to make sure there are not more global tools installed), create a new "Cordova" folder, use coho to check out all repositories there, then create a new mobile-spec project. Report each problem you encounter please and document all the commands you run. Thanks.

@janpio Hi Jan, following are the detailed steps I tried:

Installed latest node version v10.14.0
Created a new root folder named "cordova_src"
Navigated to root folder and ran the command - "coho repo-update -g -r all"
Navigated to 'cordova-cli' inside root folder and ran the command - "npm install"
Navigated to 'cordova-common' inside root folder and ran the command - "npm install"
Navigated to 'cordova-js' inside root folder and ran the command - "npm install"
Navigated to 'cordova-android' inside root folder and ran the command - "npm install"
Navigated to 'cordova-mobile-spec\createmobilespec' inside root folder and ran the command - "npm install"
Navigated to root folder and ran the command - "node ./cordova-mobile-spec/createmobilespec/createmobilespec.js --android --forceplugins"

On following these steps, i got the error - "Error: Module cordova-lib installed in cordova-plugman is not npm-linked. I recommend you run "coho npm-link".

Even if i run coho npm-link from root folder or from cordova-plugman folder, this issue still exists.

NOTE: I also get an error stating "Error: Cannot find module 'elementtree'
at Function.Module._resolveFilename (internal/modules/cjs/loader.js:580:15)
at Function.Module._load (internal/modules/cjs/loader.js:506:25)

at Object. (D:\Gandhi\Cordova\Cordova_Releases\cordova-common\src\ConfigParser\ConfigParser.js:20:10)"

when I run cordova -version command from root folder. Am i missing something in installation and setup?

janpio · 2018-11-29T16:22:43Z

Steps 4-7 are not necessary, the first error you get also a problem of outdated instructions.

Please check the updated READMEs at https://github.com/apache/cordova-mobile-spec and https://github.com/apache/cordova-mobile-spec/tree/master/createmobilespec. My PR got merged a few hours ago.

Hi @janpio , I followed the exact steps as mentioned in the link - https://github.com/apache/cordova-mobile-spec/blob/master/createmobilespec/README.md#requirements-and-preparation

While trying to execute the command - "node cordova-mobile-spec/createmobilespec/createmobilespec.js --android", I m still getting the same error as mentioned earlier.

The complete error trace is as follows:

Unhandled error. (The platform "android" does not appear to be a valid cordova platform. It is missing API.js. android not supported.)

Am i missing any prerequisites? Any thoughts?

I recall having this issue when testing with master branch of cordova-android. For now can you try it on the 7.1.x branch?

gandhirajan · 2018-12-02T14:24:17Z

@brodybits Hi Chris, Thanks for the response. This was working for me couple of patches back. Could you please let me know the exact branch path and what needs to be updated to get it tested for a specific version?

I would suggest divide and can conquer to help pinpoint where it went wrong. I would sometimes go back to where it was working and then move forward 20-30 % at a time to find the point of failure. We want to test what we will release before releasing it.

Thanks @gandhirajan, now that you have set it up following the new instructions, we have something we can compare. When I find the time, I will try to reproduce again.

If what @brodybits says applies, switching cordova-android to the 7.1.x branch should be enough.

janpio · 2018-12-02T18:38:12Z

@gandhirajan I can reproduce what you are getting for --android.

For --browser it works with no errors, which probably means that the error is not generally with createmobilespec.js, but in the specific conditions of --android - which is a good thing.

Update: tried --ios as well, which has also has problems with a missing package, but a different one than --android:

And what @brodybits suggested with switching to cordova-android 7.1.x (git checkout 7.1.x in /cordova-android) indeed fixes the problem and makes the script succeed for Android.

That should give us some information to understand what is going wrong here.

Investigation where the error is coming from:

Last output before error is iOS project created with cordova-ios@5.0.0-dev.
Code for this lives at:
https://github.com/apache/cordova-ios/blob/62ebfbd74aff11b9fa0ca26685ee0578ecd9150f/bin/lib/create.js#L255-L262
... which is the last call of createProject:
https://github.com/apache/cordova-ios/blob/62ebfbd74aff11b9fa0ca26685ee0578ecd9150f/bin/lib/create.js#L198-L239
... which is called in createPlatform:
https://github.com/apache/cordova-ios/blob/2cd93097ec5d5989bc758f15db75011829c84c2b/bin/templates/scripts/cordova/Api.js#L113-L135
So we know what happens after that output:
https://github.com/apache/cordova-ios/blob/2cd93097ec5d5989bc758f15db75011829c84c2b/bin/templates/scripts/cordova/Api.js#L124-L129
The crashing command seems to be:

                var PlatformApi = require(path.resolve(destination, 'cordova/Api'));

This requires C:\Projects\cordova5\mobilespec_ios_manual\platforms\ios\cordova\Api.js in this case (which is the same file being executed, but now inside the installed platform). unorm is the first dependency "non-system" dependency in this file.

Yep, for cordova-android the first require in the file is cordova-common: https://github.com/apache/cordova-android/blob/8a4ae311ce165e31f0511ae43274aa52d3773fd2/bin/templates/cordova/Api.js#L24

So now I know why this is crashing: Api.js in the platform does not have its dependencies available. Now to find out why.

janpio · 2018-12-02T22:14:45Z

I now have 2 apps with the Android platform added, one with master and one with 7.1.x: master is missing node_modules in platforms/android/cordova (which is created from https://github.com/apache/cordova-android/tree/master/bin/templates/cordova).

In 7.1.x this was copied there with this line:
https://github.com/apache/cordova-android/blob/7.1.x/bin/lib/create.js#L171

In master this is behind if (options.copyPlatformNodeModules):
https://github.com/apache/cordova-android/blob/master/bin/lib/create.js#L171

This was added in apache/cordova-android#536 by @erisu with the comment:

When platform is installed though CLI, cordova platform add android, the copy node_modules step is no longer valid as dependencies are now at the project level.

The step is required only when the create binary from the platform repo is called.

I was using the CLI to add the platform (C:\Projects\cordova5\cordova-cli\bin\cordova platform add "C:\Projects\cordova5\cordova-android" --verbose), so something went wrong there I guess :/

janpio · 2018-12-02T22:19:56Z

Further discussion on how to solve the underlying CLI/Android problem is moved here:
apache/cordova-cli#362 (comment)

gandhirajan · 2018-12-08T08:17:41Z

@janpio thanks for the info Jan. As you said, it works fine for browser platform. I guess we can close this once apache/cordova-cli#362 is sorted out. Please correct me if I m wrong

janpio · 2018-12-08T11:46:12Z

Yep, apache/cordova-cli#362 and apache/cordova-cli#363 have to be fixed for this to work again. The second one is Windows only I think.
