In a virtual environment I get the error
path/to/python: Error while finding module specification for 'pip' (AttributeError: module '__main__' has no attribute '__file__')
when I run commands like
python -m pip install --upgrade pip
python -m pip freeze
However, when I run the same command with pip it works, e.g.
pip install --upgrade pip
pip freeze
python is the same as python3, version is 3.8.12, I reinstalled pip using
pip install --force-reinstall pip
pip version is 21.3.1.
What else can I do so the python -m pip commands work again?
