PlayOnLinux not working with on wxPython 4.1.0 - ImportError: No Module named wxversion, needs to be wx.version instead

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

$ apt-cache policy playonlinux

playonlinux:

  Installed: 4.3.4-1ubuntu1

  Candidate: 4.3.4-1ubuntu1

  Version table:

 *** 4.3.4-1ubuntu1 500

        500 http://us.archive.ubuntu.com/ubuntu focal/multiverse amd64 Packages

        500 http://us.archive.ubuntu.com/ubuntu focal/multiverse i386 Packages

        100 /var/lib/dpkg/status



$ which playonlinux

/usr/bin/playonlinux



# *** note: i'm using pyenv ***



$ pyenv local 2.7.18



$ which python2

/home/dever/.pyenv/shims/python2



$ python2 -V

Python 2.7.18



$ pyenv local 3.8.3



$ which python3

/home/dever/.pyenv/shims/python3



$ python3 -V

Python 3.8.3

Installed Python 3.8.3 configuration has wxPython 4.1.0

$ python

Python 3.8.3 (default, Jul 16 2020, 20:35:40) 

[GCC 9.3.0] on linux

Type "help", "copyright", "credits" or "license" for more information.

>>> import wx

>>> print(wx.version)

<function version at 0x7ff77d3cbd30>

>>> print(wx.version())

4.1.0 gtk3 (phoenix) wxWidgets 3.1.4

>>> quit()

Consequently, the playonlinux command fails with this error:

$ playonlinux

Please install python before trying to run this program

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

For additional context also see: https://discuss.wxpython.org/t/where-to-obtain-wxversion-py/28752

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 `system` is first choice in global configuration: `pyenv global system` or set the python version for the current shell with `pyenv shell system`. If you use `global` you 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 global command and making system first as follows (Note: the command you execute will depend on the versions of python you have installed):

pyenv global system 3.8.3 2.7.18 anaconda3-2019.10

Investigating the problem more, I reviewed the following files:

/usr/share/playonlinux/bash/find_python

/usr/share/playonlinux/python/check_python.py

I 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. playonlinux depends on the system python.

Initially I thought that running the pyenv local system would solve the problem, but because of how pyenv works this was not the case.

To ensure that /usr/share/playonlinux/bash/find_python resolves to the system installed python, you must make sure that pyenv global is set with system as the first choice.

Many thanks to @N0rbert !!
