Hi, thanks a lot for the report! It seems like a flake8/vscode issue. I am going to open this issue in the upstream repo. And report back.

@sobolevn Thanks, I saw the related issues so I will upgrade my dependencies to latest version as it recommended in adamchainz/flake8-comprehensions#193 and try again

Or do you need to make changes?

ae-lexs on 12 Nov 2019

Nope, let's start from this solution. In case it works, can you please send us a pr with the fix?

sobolevn on 12 Nov 2019

@sobolevn The problem persists, I can't see the errors in VSCode, but now I can see the result of the command flake8 --bug-report

I only updated the following information:

If you just run flake8 . does it work? Does it show the error messages?

orsinium on 15 Nov 2019

Do you have a flake8 config? Could you show it, please?

I am pretty sure that this is a vscode / plugin / configuration issue.

It does work for me with no problems.

sobolevn on 15 Nov 2019

I only installed the Python extension and I run the linter in every save.

I also have other projects with Flake8 or Pylama and them works fine :disappointed:

ae-lexs on 16 Nov 2019

Does raw flake8 (without any plugins) work for you?

sobolevn on 16 Nov 2019

Ok, let's mark it as resolved. Feel free to reopen.
