Yarn: Some dependencies don't get installed if they're shared between a regular and a devDependency

Bug

What is the current behavior?

Take the following package.json:

{
  "dependencies": {
    "babel-core": "6.17.0"
  },
  "devDependencies": {
    "eslint": "3.3.1"
  }
}

Running yarn install leads to the following yarn.lock https://gist.github.com/bouk/b96cf30321d696724ef926367c5af879

Yarn LS tells me the following https://gist.github.com/bouk/6514ee7102c7c386cf29f351747c8e54

If I remove node_modules and then run yarn install --production, I will end up with a situation where escape-string-regexp is missing, even though it's a dependency of babel-core, through babel-code-frame->chalk->escape-string-regexp

What is the expected behavior?

escape-string-regexp is installed

Please mention your node.js, yarn and operating system version.

Something similar seems to happen with a global npm install of yarn.

$ npm install -g gulp
$ npm install -g yarn

Then if I run yarn I get this error

$ yarn
/usr/local/lib/node_modules/yarn/bin/yarn.js:48
      throw err;
      ^

Error: ENOENT: no such file or directory, open

    at Object.<anonymous> (/usr/local/lib/node_modules/yarn/node_modules/chalk/index.js:2:26)

I'm guessing because escape-string-regexp was already installed as a dependency of gulp

I have the same issue. yarn --production is confused with dev dependencies.
Workaround for now is to install all dependencies... less than ideal.

I am also getting same error while executing yarn command.

$ yarn
/usr/local/lib/node_modules/yarn/bin/yarn.js:48
      throw err;
      ^

Dupe of #761.

[vaikuntn]

I am able to solve this issue by following given steps.

• Uninstalled yarn by executing following command.
  sudo npm uninstall -g yarn
• Deleted following files/folders from home folder..

.yarn
.yarn-cache
.yarn-config
.yarnrc

• Executed npm cache clean (I am not sure whether this is required or not)
• Now install yarn again by executing following command.
  sudo npm install -g yarn
  This should solve below given issue. try executing yarn command.

$ yarn
/usr/local/lib/node_modules/yarn/bin/yarn.js:48
      throw err;
      ^
Error: ENOENT: no such file or directory, open '/usr/local/lib/node_modules/yarn/node_modules/chalk/node_modules/escape-string-regexp/index.js'
    at Error (native)
    at Object.fs.openSync (fs.js:585:18)

I am just suspecting the root cause of this is due to different node versions while installing the yarn package. i.e. when I installed yarn first time I had node v4.3.3 and later I moved to 6.3.3 and tried to execute yarn, got few errors so I uninstalled and reinstalled yarn. From this time I am getting ENOENT error while executing yarn command.

@vaikuntn What you're describing seems to be a different issue about corrupt dependencies with installing yarn. This isse (as is #761) is about Yarn installing the incorrect dependencies when running yarn install --production (without error), and then throwing an error when running a subsequent script depending on the missing dependency. The generic error just occurs when a dependency cannot be found.

@davidowens, what @vaikuntn suggested: deleting .yarn/.yarn-cache/.yarn-config fixed it for me

NOTE: nothing related to sudo was required

[davidowens]

Yes, I just tried that and it has worked for me too. 👍 for not needing sudo because that make it much easier for me to get it running on the build server

[yonglijia]

please try to intall it by brew

761 is closed, but yarn --prod is still broken for me (https://github.com/yarnpkg/yarn/issues/761#issuecomment-260975012). Is this the correct issue for it?

[androa]

Now that #761 is reopenend, I suggest merging this into #761 as they are about the exact same problem.

Fixed via #2116.
