rm: cannot remove 'project_new/.pytest_cache/*': Permission denied

After first run of command make test from 3 step in contribution guide, second run failed with a list of errors:

...
rm: cannot remove 'project_new/.pytest_cache/*': Permission denied
...
rm: cannot remove 'project_new/.mypy_cache/*': Permission denied
...

I'm on Linux, Ubuntu 18.04 and I think this issue is related to this issue moby/moby#3124

Also, this is not reproducible on MacOS

Hi 👋

This error connected only with linux. Docker create all files as a root user and when u try remove them u got current error.

I know some solution:

• run all with sudo 😅
• disable cache for pytest and mypy

mypy you_project --cache-dir=/dev/null
pytest -p no:cacheprovider

Please, text me back if any of these approaches has helped you

Docker should be made to use a special docker user instead of creating files as root
