ubuntu - 在 Ubuntu 18.04 上的 Python 3.7 上安装 wxPython

Question

我在 Python 3.7.5 上安装 wxPython4 时遇到问题

$ pip3 install wxpython
Defaulting to user installation because normal site-packages is not writeable
Collecting wxpython
  Using cached wxPython-4.1.0.tar.gz (65.8 MB)

      File "/usr/lib/python3/dist-packages/Cython/Compiler/ExprNodes.py", line 2844
        await = None
              ^
    SyntaxError: invalid syntax

我不确定是什么问题。在 Python3 中所做的更改，所以 await 现在是一个特殊的关键字。它是否以某种方式将 Python2 与 Python3 混淆了？

如果我按照这里的建议做

https://askubuntu.com/questions/1073145/how-to-install-wxpython-4-ubuntu-18-04

First I found it by:

sudo apt search python3-wx I installed the latest wxpython with:

sudo apt-get install python3-wxgtk4.0 python3-wxgtk-webview4.0 python3-wxgtk-media4.0 You may also try synaptic to install it that way if you prefer.

我得到一个不同的错误

ModuleNotFoundError: No module named 'wx._core'

这可能是由于缺少依赖项。

我认为这是由于 Cython 0.26 和 Python 3.7 之间的不兼容问题。请参阅有关 SerpentAI 的答案.
