Error when creating a new project #2751

SeanBannister · 2017-07-09T09:50:19Z

Is this a bug report?

Yes

Can you also reproduce the problem with npm 4.x?

This bug is not reproducible with NPM. It only affects create-react-app when Yarn is installed.

Environment

node -v: 6.11.0
npm -v: 4.6.1
yarn --version:
Tested with:
0.27.5
0.26.0
0.25.1
npm ls react-scripts: Not applicable, doesn't get this far to check.
Operating system:
Windows 8.1 Pro

Steps to Reproduce

Install create-react-app npm install -g create-react-app
Install yarn via the windows .msi file.
Open command prompt and run: create-react-app myapp

Expected Behavior

New project is created.

Actual Behavior

The following error is encountered.

Aborting installation.
Unexpected error. Please report it as a bug:
{ Error: Cannot find module 'L:\myapp\node_modules\react-scripts\scripts\init.js'
    at Function.Module._resolveFilename (module.js:469:15)
    at Function.Module._load (module.js:417:25)
    at Module.require (module.js:497:17)

    at process._tickCallback (internal/process/next_tick.js:109:7) code: 'MODULE_NOT_FOUND' }

Full output from the command line here.

As mentioned above this only happens when Yarn is installed and therefore create-react-app uses it for creating the project. If I uninstall Yarn the process completes successfully with NPM.

I'm looking for guidance on how I should attempt to debug this. This might end up being a Yarn issue.

The text was updated successfully, but these errors were encountered:

Install create-react-app 1.3.3 via the Windows .msi file.

I didn't fully get that part. Where did you find this .msi file?

SeanBannister · 2017-07-09T18:44:43Z

Sorry I clearly wasn't thinking when I typed that, here's what I meant to write:

Steps to Reproduce

Install create-react-app npm install -g create-react-app
Install yarn via the windows .msi file.
Open command prompt and run: create-react-app myapp

gaearon · 2017-07-09T19:02:09Z

I’d appreciate if you could cross-post this in Yarn repo.
I don’t think it’s a bug on our side, but we’ll want to keep track of it.

I get this same error without yarn

andywillis · 2017-08-09T13:42:24Z

@gaearon , I'm getting this error with npm v3/4/5 (node v6 and 8), and yarn (npm uninstalled), Windows 7 x64. At first I thought it was an issue with my network connection, or a problem with npm, or my virus checker, but npm/yarn will quite happily install something like preact-cli without any problems. It's got me completely foxed because it worked fine in the past.

It never aborts in the same place in the installation, but it's always the same error:

Can you try clearing your npm and Yarn cache?

andywillis · 2017-08-09T13:55:55Z

Yes. I tried that too. Same error, but this time it aborted immediately instead of running through a few packages first.

We can't help more since the error is so transient. It might be caused by a buggy npm or Yarn version, a bad npm registry proxy, a bad internet connection, etc.
