Hi,
I'm trying to use a (non-Debian) python system built on python 3.8. Debian's
default is currently 3.9 so I am advised to use a virtual environment. Being
a newbie, I searched around and found a writeup covering several different
virtualization tools [1]. Note I am using Debian 'sid'.
I can use the tool "virtualenv" to create a virtual environment for default
python:
steve@riemann:/tmp$ virtualenv blah
created virtual environment CPython3.9.1.final.0-64 in 77ms
creator CPython3Posix(dest=/tmp/blah, clear=False, no_vcs_ignore=False,
global=False)
seeder FromAppData(download=False, pip=bundle, setuptools=bundle,
wheel=bundle, via=copy, app_data_dir=/home/steve/.local/share/virtualenv)
added seed packages: pip==20.1.1, pkg_resources==0.0.0,
setuptools==44.0.0, wheel==0.34.2
activators
BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator
But not for python 3.8:
steve@riemann:/tmp$ virtualenv -p python3.8 blah38
RuntimeError: failed to find interpreter for Builtin discover of
python_spec='python3.8'
I have installed literally all the Debian python packages whose name contains
'python3.8'. A very short list:
ii libpython3.8:amd64 3.8.7-1
amd64 Shared Python runtime library (version 3.8)
ii libpython3.8-dev:amd64 3.8.7-1
amd64 Header files and a static library for Python (v3.8)
ii libpython3.8-minimal:amd64 3.8.7-1
amd64 Minimal subset of the Python language (version 3.8)
ii libpython3.8-stdlib:amd64 3.8.7-1
amd64 Interactive high-level object-oriented language (standard
library, version 3.8)
ii python3.8 3.8.7-1
amd64 Interactive high-level object-oriented language (version 3.8)
ii python3.8-dev 3.8.7-1
amd64 Header files and a static library for Python (v3.8)
ii python3.8-minimal
I have also tried the module 'venv':
steve@riemann:/tmp$ python3.8 -m venv v38
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.
apt-get install python3-venv
You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.
Failing command: ['/tmp/v38/bin/python3.8', '-Im', 'ensurepip', '--upgrade',
'--default-pip']
steve@riemann:/tmp$ python3.8 -m venv blah38

Failing command: ['/tmp/blah38/bin/python3.8', '-Im', 'ensurepip', '--
upgrade', '--default-pip']
Note that I do have 'python3-venv' installed, but it is the 3.9 version:
ii python3-venv 3.9.1-1
amd64 pyvenv-3 binary for python3 (default python3 version)
Is there something I've missed?
Thank you,
-Steve
