试图在Windows上下载wxpython时出错

Question

完全是Python的新事物，在命令行中运行命令“ Pip install -u wxpython”，这是我遇到的错误：

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

Answer 1

我的安装程序看不到新的“ VisualStudio”。这对我有帮助。也许你也是。

1. 下载来源：
   

   
   

2. 安装：

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

3. 测试：

     python -c“导入wx; print（wx.version（））;”
    

如果一切都正确，则可以提出输出： 4.1.2a1 MSW（凤凰）WXWIDGETS 3.1.5
