npm@5 TypeError: Cannot read property 'version' of null #298

yvele · 2017-06-01T14:47:17Z

Looks like using npm 5 we have a problem.

package_json.version at line 262 is undefined and throws at line 270

Main NPM issue:

npm5 package-lock.json uses resolved URL for version property of existing node_modules npm/npm#16926

sgtcoolguy · 2017-06-02T16:54:11Z

I think this is due to npm5 using a URL value for the version property in package.json files now.

There's a hint in the full error output below:

Cannot read property 'version' of null

Specifically, you see: node-pre-gyp ERR! node-pre-gyp -v vhttps://registry.npmjs.org/node-pre-gyp/-/node-pre-gyp-0.6.34.tgz

Looking at the package.json files in my node_modules folder after an npm5 install, I see things like:

{
  "version": "https://registry.npmjs.org/set-blocking/-/set-blocking-2.0.0.tgz"
}

So semver.parse is returning null because these aren't really semantic versioning strings, but urls of resolved packages.
Ultimately I'm not sure if this is a node-pre-gyp "bug" that you'd need to add a workaround for, or it's an npm5 bug. Certainly feels more like an npm bug to me, but then maybe they need/intend for the version value to be a URL for the future.

springmeyer · 2017-06-02T17:31:57Z

Thanks for the report and digging everyone. As the current maintainer of node-pre-gyp my preference here is to:

Recommend people workaround for now by avoiding npm5
Wait for this to be fixed in npm5: npm5 package-lock.json uses resolved URL for version property of existing node_modules npm/npm#16926

floriantraber · 2017-06-03T19:28:07Z

workaround: Remove the lock file.

rm .\package-lock.json

Alexis-Bize · 2017-06-04T00:07:37Z

Worked for me, thanks @floriantraber!

mattbell87 · 2017-06-05T00:54:57Z

@floriantraber Thanks!

dhniels · 2017-06-05T19:38:05Z

If you remove the lock file doesnt it just regenerate it again after running npm install?

borislemke · 2017-06-09T15:07:22Z

in my case the package-lock.json file got included in the project's commit. When cloning the repo on another machine and doing npm i, this error would be thrown. We added the lock file to .gitignore and all works well.

alexjlockwood · 2017-06-09T15:15:29Z

@borislemke That may work as a temporary solution, but the package-lock.json file is meant to be committed to source control.

maifs · 2017-06-10T12:22:22Z

Same issue in here..

alexjlockwood · 2017-06-14T12:32:05Z

I added package-lock=false to the .npmrc file in my repo's root directory in order to temporarily workaround the issue. Seemed cleaner than adding it to the .gitignore. :P

dustintheweb · 2017-06-18T15:30:56Z

@alexjlockwood worked like a champ

See mapbox/node-pre-gyp#298 for details.

…-work-around-node-pre-gyp-bug do not use `package-lock.json` (workaround for `node-pre-gyp` bug on npm5: mapbox/node-pre-gyp#298) (fixes #439)

lmuzquiz · 2017-09-05T14:51:03Z

I was dealing with this errors many hours until i deleted my package-lock.json file and then ran npm install again. I know the file is re-generated with each npm install but i dont get the node pre gyp errors anymore. So go figure...
Thanks to all of you.

springmeyer · 2017-09-07T20:26:43Z

In addition to removing package-lock.json I've found another workaround.

I was able to replicate this on OS X with:

node v8.4.0
npm 5.3.0

this package.json:

{
  "name": "master",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "sqlite3": "https://github.com/mapbox/node-sqlite3/tarball/d18c1e97de9478aab27067638899b068e6d8ed03"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

And by seeding the node_modules/node-pre-gyp folder with node-pre-gyp@0.6.36.

It seems that something about the install noticing node-pre-gyp already in the node_modules (which is okay and often the case) triggers this odd behavior in npm.

Locally I've been able to solve by doing:

{
  "name": "master",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "sqlite3": "https://github.com/mapbox/node-sqlite3/tarball/master"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

Which includes TryGhost/node-sqlite3@34e1a40. So, my hunch is that npm ls is involved here somehow.

Thank you @floriantraber for pointing out the removal of package-lock.json. I did that and was still getting the error, but when I removed my node_modules folder and then ran npm install again, It worked. So remove both package-lock.json and node_module folder and ran npm install and that should work.

skylarmb · 2017-10-30T21:30:27Z

I fixed this by updating to fsevents@1.1.2 which fixes this: fsevents/fsevents#172
