Please could you provide the contents of your workspace settings (settings.json)

Of course, thank you for fast response

• Do you have a directory named .env in your workspace?
• Please could you try the following, create an empty file named .envFile in your workspace and add the following into your workspace settings settings.json:

"python.envFile": "${workspaceFolder}/.envFile"

[pscelzamelo]

That made the fix. Test discovery and execution is running as normal.

Thanks very much for the fast support, my env is up and running for now!

Did I screw up anything in my configs or actually helped find out a bug?

[DonJayamanne]

Do you have a directory named .env in your workspace?

Please could you confirm the above.

[pscelzamelo]

Yes I do, I used to setup virtualenv on .env/, then activate it on terminal then opening code . to start working

[DonJayamanne]

helped find out a bug?

Thanks, yes you have helped us find an interesting bug. Looks like a nodejs bug of some sorts. Will have to implement a workaround. Thanks, should be easy enough to fix.

[pscelzamelo]

Happy for that! Thank you very much!

It looks like I have hit a similar bug to this. For me the symptom was after creating a virtualenv in .env/, pylint stopped running/outputting anything. There was also no output at all in the OUTPUT tab and I had similar JS errors to @pscelzamelo in the debugging windows.

After creating the empty .envFile and adding the additional configuration line to the workspace settings, pylint is now working as expected.

[DonJayamanne]

@aidan- looks like you have encountered the same issue as #435

[lalvarezguillen]

I got here from #482 , and just wanted to confirm that this solution worked for me as well. None of the Python linters or Mypy were working, and I had a .env directory in the workspace.

Thanks for the solution!

[VFagundes]

I had the same problem, the .envFile worked for me too 😄
