[SOLVED] Pip is not found after creating new python virtual environment

Issue

I'm trying to create new Python virtual environment, but I have problems with pip.

I want my virtual environment to run on Python 3.10, but my default system Python version is 3.9.5. So I downloaded Python 3.10 with

sudo apt-get install python3.10

and then i run

python3 -m virtualenv venv --python=python3.10

to create virtual environment.

The problem is, when I try to use pip I get an error:

Traceback (most recent call last):
  File "/home/<my user name>/venv/bin/pip", line 5, in <module>
    from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip'

I tried running

python -m ensurepip --upgrade

but got an error:

/home/pablo/venv/bin/python: No module named ensurepip

Also running whereis pip shows, that there are some pips in the virtual environment.

pip: /usr/bin/pip /home/<my user name>/venv/bin/pip3.10 /home/<my user name>/venv/bin/pip /usr/share/man/man1/pip.1.gz

Also, when I create virtual environments with my default python interpreter, everything works perfectly fine.

Solution

I would recommend using pyenv with pyenv-virtualenv. In my experience it's just too much work to go manual. Sorry I know this is not a true answer, but having wasted hours and hours on similar issues, I feel like sharing )
