The latest version of wxPython doesn't support the wxversion module. Instead the information is available as wx.version.
Is there any suggested work around to this? Thanks!
My environment is Ubuntu 20.04 LTS, pyenv, python 3.8.3, python 2.7.18, wxPython 4.1.0

Consequently, the playonlinux command fails with this error:

NOTE: For those struggling to install wxPython on Ubuntu 20.04 LTS due to GTK+ error *** Could not run GTK+ test program, checking why...
Try this command (found here: https://wxpython.org/pages/downloads/)
pip install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-20.04 wxPython

playonlinux installed initially as follows, but reinstalled with standard repository on Ubuntu 20.04 LTS (i upgraded from 19.10):
The version of playonlinux I'm running is for Ubuntu 18.04 (Bionic Version) downloaded from here: https://www.playonlinux.com/en/download.html
For the Bionic version
Type the following commands:
wget -q "http://deb.playonlinux.com/public.gpg" -O- | sudo apt-key add -
sudo wget http://deb.playonlinux.com/playonlinux_bionic.list -O /etc/apt/sources.list.d/playonlinux.list
sudo apt-get update
sudo apt-get install playonlinux
Maybe playonlinux is superseded by the flatpak version?
Looking at the Github link on https://www.playonlinux.com takes you to https://github.com/PhoenicisOrg/ which suggest that perhaps the solution is to migrate to the flatpak version:
Short answer: The problem is related to pyenv, make sure
systemis first choice in global configuration:pyenv global systemor set the python version for the current shell withpyenv shell system. If you useglobalyou only have set it once.Short explanation: Use
pyenv global system (2nd) (3rd)...to ensure that playonlinux finds the right python; where (2nd) and (3rd) are pyenv version numbers for your installed interpreters.Long explanation: After getting the curtain rolled back with the really helpful posts by @N0bert, I've discovered that in my case the problem is pyenv related.
Specifically, I can resolve my issue by using the
pyenv globalcommand and makingsystemfirst as follows (Note: the command you execute will depend on the versions of python you have installed):Investigating the problem more, I reviewed the following files:
/usr/share/playonlinux/bash/find_python/usr/share/playonlinux/python/check_python.pyI made my own copies of these to understand the error better. It turns out the wxversion error is really misleading, the real problem is finding the right python shell to run.
playonlinuxdepends on the system python.Initially I thought that running the
pyenv local systemwould solve the problem, but because of how pyenv works this was not the case.To ensure that
/usr/share/playonlinux/bash/find_pythonresolves to the system installed python, you must make sure thatpyenv globalis set withsystemas the first choice.Many thanks to @N0rbert !!
You have to simply install latest PlayOnLinux 4.3.4 from the official repository with
and it will depend on Python 2 as it is designed to be.
The complete command to install PlayOnLinux with dependencies is below:
(from command above you can see that two wx-related packages -
python-wxgtk3.0 python-wxversionare listed)
