@Adem-Kri thank you for reporting the issue, the widget template for the generation works fine for me locally and through ci. Do you mind trying again in a completely new directory (based on the logs it looks like it might have been used before).

For additional information all the dependencies that errored during the build are explicitly declared, it looks like installing them was skipped:

• (ex: @testing-library/react): https://github.com/eclipse-theia/generator-theia-extension/blob/2ca151998f88fad59b5261a3476efc7cc67f59c7/src/app/index.ts#L249

[Adem-Kri]

@vince-fugnitto I closed the issue by mistake, can you reopen it, and of course I don't mind retrying what you asked me for just can you clarify more what am supposed to do

[vince-fugnitto]

I don't mind retrying what you asked me for just can you clarify more what am supposed to do

@Adem-Kri sure:

• create a new directory on your filesystem
• navigate to that directory
• perform yo theia-extension and select the widget template
• let the generation finish and build complete

[Adem-Kri]

@vince-fugnitto As you see I get the same output. it all works fine until reaching browser-app

[vince-fugnitto]

@Adem-Kri you're behind a proxy I assume given the fact you can't reach github.com?

• https://github.com/eclipse-theia/theia/discussions/11813

Edit: Ah looks like you already opened the discussion, you can continue it there.

[Adem-Kri]

what I can't understand is that am able to clone repo's and install using npm or yarn , I can accede github and also setted this :

git config --global http.proxy http://login:password@company's_domain:port(8080)

Is there something I am missing @vince-fugnitto and thank you for your precious time.

[msujew]

@Adem-Kri Because yarn doesn't use the git configured http-proxy, but instead the HTTP_PROXY env variables. Please see my answer here.
