尝试在 Windows 上下载 wxPython 时出错

Question

对 python 完全陌生，运行在命令行中使用“pip install -U wxPython”命令，这是我得到的错误：

C:\Users\Pikachu>pip install -U wxPython

我的安装程序没有看到新的“VisualStudio”。这对我有帮助。也许你也是。

下载源： wxPython-4.1.2a1-cp310-cp310-win_amd64.whl

安装：

 pip install _your_path_to_src_\wxPython-4.1.2a1-cp310-cp310-win_amd64.whl

测试：

 python -c "import wx; print(wx.version());"

如果一切正确，可能的输出：4.1.2a1 msw (phoenix) wxWidgets 3.1.5
