Will look into this. In the meanwhile, can you try installing mysqlclient directly with nix please? This can be done by using specifying “pkgs.python311Packages.mysqlclient” in dev.nix’s packages section. let me know of it doesn’t work!

My dev.nix file contain
pkgs.pkg-config
pkgs.python311Packages.pydevtool
pkgs.libmysqlclient
pkgs.python311Packages.mysqlclient
pkgs.python311Packages.wheel

but not work, when I try run python manage.py runserver I got this error
Did you install mysqlclient?

When I try run pip install mysqlclient I got this error:
Exception: Can not find valid pkg-config name.
