最近需要安装wxPython，熟练的在命令行窗口用pip install wxPython安装，试了好几次一直，报错
然后尝试去官网下载源文件，再安装
下载完源文件，在命令行窗口python的安装目录/Scripts下执行pip install wxPython-4.1.0-cp37-cp37m-win_amd64.whl
报错：ERROR: wxPython-4.1.0-cp37-cp37m-win_amd64.whl is not a supported
然后，在网上搜索这个报错的解决问题，看到各位大佬说：在shell中输入import pip; print(pip.pep425tags.get_supported())可以获取到pip支持的文件名还有版本
输入 print(pip.pep425tags.get_supported())命令，报错：AttributeError: module 'pip' has no attribute 'pep425tags'
继续找其他大佬的解决办法：在shell中输入import pip._internal 和print(pip._internal.pep425tags.get_supported())可以获取到pip支持的文件名还有版本
继续操作，报错：AttributeError: module 'pip._internal' has no attribute 'pep425tags'
好吧，开始怀疑人生了，怎么报错越来越多了
继续找其他大佬的说法，18.0以上的pip这两个是行不通的，OK
继续尝试：用python -m pip debug --verbose这个命令试试
总算不报错了：（运行结果如下）

总算查看到了本机pip支持的文件名还有版本
修改wxPython-4.1.0-cp37-cp37m-win_amd64.whl文件名字为wxPython-4.1.0-cp37-cp37m-win32.whl
在命令行窗口python的安装目录/Scripts下执行pip install wxPython-4.1.0-cp37-cp37m-win32.whl
如图所示：
不容易啊，总算安装成功了
