Creating a virtualenv in Python 2.7 fails (?)

[stzanos95]

Hi there, I just got an Ubuntu 22.04 machine with Python 3.10 preinstalled. Work projects requires me to use Python 2.7 and 3.9.

Creating a virtual environment with 3.x versions seems to work just fine:

$ pyenv virtualenv 3.9.16 py39
$ pyenv versions
  system
* 2.7.18 (set by /home/stzanos/.pyenv/version)
  3.8.10
* 3.9.16 (set by /home/stzanos/.pyenv/version)
  3.9.16/envs/py39
  3.10.6
  py39

However, when trying to create in 2.7:

$ pyenv virtualenv 2.7.18 py27
Traceback (most recent call last):
  File "/home/stzanos/lib/python/site.py", line 73, in <module>
    __boot()
  File "/home/stzanos/lib/python/site.py", line 3, in __boot
    import os
  File "/home/stzanos/.pyenv/versions/2.7.18/envs/py27/lib/python2.7/os.py", line 49, in <module>
    import posixpath as path
ImportError: No module named posixpath
error: failed to install pip via get-pip.py

Any idea why this is happening? I would like to work in a virtual environment which python -> Python 2.7.18 and python3 -> 3.9.16.
I'd like this in order to open my projects in PyCharm and being able to use both.
