Ubuntu 20.04 has Python 3.6 and Python 3.8 support. Command
python3 -m venv my_venv creates virtual environment with python 3.8 and it works as expected.
python3.6 -m venv my_venv3.6 does not work. The response I get is
/usr/bin/python3.6: No module named venv.
I tried using
virtualenv --python=/usr/bin/python3.6 my_venv3.6, which results in:
RuntimeError: failed to query /usr/bin/python3.6 with code 1 err: ...
I also tried installing
sudo apt install python3.6-venv which results in:
Reading package lists... Done Building dependency tree Reading state information... Done Package python3.6-venv is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'python3.6-venv' has no installation candidate
Note that running
python3.6 starts interactive python prompt with Python 3.6.9. I can also run scripts this way, so it seems that Python 3.6 is indeed usable on my system.
How can I start Python 3.6 virtual environment on Ubuntu 20.04?
