Error: spawn yarn ENOENT

[PhilippeDEFORGE]

Dear all, I would like to discover theia but I'm facing this issue. yarn is installed globally (version 1.22.22) and in the PATH but the issue is still there. Any Idea ?

Thanks

Node.js v18.20.5

It indeed looks like yarn is not installed correctly.
yarn --version
In the same terminal works?

Hi Jonas,

Yes, it works:

C:\Users\philippe\my-theia-app>yarn --version
1.22.22

[JonasHelming]

Can node generally spawn yarn?

node -e "require('child_process').spawnSync('yarn', ['--version'], { stdio: 'inherit' })"

If this fails with ENOENT, it confirms Node.js cannot find Yarn, even though it's in the PATH.

[PhilippeDEFORGE]

I've run the following command :

node -e "require('child_process').exec('yarn --version', (err, stdout, stderr) => { if (err) { console.error('Yarn not found'); } else { console.log(stdout); } })"
1.22.22

The result confirm the yarn version.

[JonasHelming]

OK, can you run in a fresh directory:
yo theia-extension --skip-install
and then
yarn install?

[PhilippeDEFORGE]

There is still one error but it seems that your workaround works.
