问题：

wxPython的最新版本不支持wxversion模块，

对此有什么建议吗？

环境是ubuntu20.04LTS，pyenv，python3.8.3，python2.7.18，wxpython4.1.0

$ apt-cache policy playonlinux


playonlinux:


 Installed: 4.3.4-1ubuntu1

$ which playonlinux

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



$ pyenv local 2.7.18

$ python2 -V


Python 2.7.18



$ pyenv local 3.8.3



$ which python3


/home/dever/.pyenv/shims/python3



$ python3 -V


Python 3.8.3

安装的python 3.8.3配置有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()

因此，playonlinux命令失败，错误为：

$ playonlinux

Please install python before trying to run this program

尝试此命令

pip install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-20.04 wxPython

有关其他上下文，请参见：https://discuss.wxpython.org/t/where-to-obtain-wxversion-py/28752

playonlinux最初的安装方式如下，但在Ubuntu 20.04 LTS (我从19.10升级)上用标准存储库重新安装：

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

也许playonlinux被flatpak取代了？

查看https://www.playonlinux.com上的Github链接，可以转到https://github.com/PhoenicisOrg/，它建议解决方案是迁移到flatpak版本：

答案1：

简短的回答：问题与pyenv相关，确保system在全局配置中是首选：pyenv global system或用shell设置当前pyenv shell system的python版本，如果使用global，你只需设置一次，

简短说明：使用 pyenv global system (2nd) (3rd)... 确保playonlinux找到正确的python；其中(2nd)和(3rd)是已安装解释器的pyenv版本号。

具体地说，可以使用pyenv global命令来解决问题，并使system优先，如下所示(注意：执行的命令取决于已安装的python的版本)

pyenv global system 3.8.3 2.7.18 anaconda3-2019.10

确保 /usr/share/playonlinux/bash/find_python 解析为已安装的系统python，你必须确保pyenv global被设置为system作为首选。

答案2：

必须从官方存储库安装最新的PlayOnLinux 4.3.4

sudo add-apt-repository multiverse


sudo apt-get install --reinstall playonlinux=4.3.4-1ubuntu1

它被设计成依赖Python 2。
