[davidkassa]

Versions

Repro steps

Using GitLab CI:

image: davidkassa/yarn-angular-cli-firebase-tools:latest
before_script:
 - node --version
 - npm --version
 - ng --version

Observed behavior

$ ng --version
ENOENT: no such file or directory, scandir '/builds/davidkassa/shot-club-web/node_modules'
Error: ENOENT: no such file or directory, scandir '/builds/davidkassa/shot-club-web/node_modules'

    at Generator.next (<anonymous>)
    at fulfilled (/usr/local/share/.config/yarn/global/node_modules/@angular/cli/models/command-runner.js:4:58)
ERROR: Job failed: exit code 1

Desired behavior

I would expect version information to be given even if there is not a node_modules/ directory present

Mention any other details that might be useful (optional)

I am getting that same error:

ENOENT: no such file or directory, scandir '/Users/david/repos/halo/frontend/node_modules'
Error: ENOENT: no such file or directory, scandir '/Users/david/repos/halo/frontend/node_modules'

The only cause I can think of is of mixing both npm and yarn to install/uninstall packages?

I have been unsuccessfully trying to upgrade from angular 5 to angular 6. Now I am trying to do a fallback. Nothing is working

I am getting this error on my WIndows dev box when calling ng --version or ng version...

I have the same problem, but the error message is different. In my case, @angular/cli was installed globally with yarn instead of npm. This command is run from VSCode terminal window. Is this a powershell compatibility issue?

It does work from within cygwin or the windows command prompt

Should this be reported in a separate bug report, related to powershell compatibility?

[baembry]

I had the same issue and solved it by changing to the root directory [cd ~/] and then running ng --version

[bgotink]

This happens in yarn 2 plug-n-play set ups as well, because there's no longer a node_modules folder in projects using yarn 2.
