Getting `project is in the MYPYPATH. Please remove it.` with latest mypy

[patrick91]

Hi there, I've got a PR that tries to update mypy to the latest version on my project but the tests fail with the following error:

strawberry is in the MYPYPATH. Please remove it. 

I'm not sure if there's a way to fix this, I'm not setting the MYPYPATH anywhere.

Full message:

There's a few similar issues in the mypy repo, like python/mypy#13214.
Seems like a fix is on the way - python/mypy#13223

thanks @Apakottur, I'll close the issue then, hopefully we get a new release of MYPY soon 😊

I think this was fixed in the last release of this project 😊 will try it soon
