最近需要安裝wxPython，熟練的在命令行窗口用pip install wxPython安裝，試了好幾次一直，報錯
然后嘗試去官網下載源文件，再安裝
下載完源文件，在命令行窗口python的安裝目錄/Scripts下執行pip install wxPython-4.1.0-cp37-cp37m-win_amd64.whl
報錯：ERROR: wxPython-4.1.0-cp37-cp37m-win_amd64.whl is not a supported
然后，在網上搜索這個報錯的解決問題，看到各位大佬說：在shell中輸入import pip; print(pip.pep425tags.get_supported())可以獲取到pip支持的文件名還有版本
輸入 print(pip.pep425tags.get_supported())命令，報錯：AttributeError: module 'pip' has no attribute 'pep425tags'
繼續找其他大佬的解決辦法：在shell中輸入import pip._internal 和print(pip._internal.pep425tags.get_supported())可以獲取到pip支持的文件名還有版本
繼續操作，報錯：AttributeError: module 'pip._internal' has no attribute 'pep425tags'
好吧，開始懷疑人生了，怎么報錯越來越多了
繼續找其他大佬的說法，18.0以上的pip這兩個是行不通的，OK
繼續嘗試：用python -m pip debug --verbose這個命令試試
總算不報錯了：（運行結果如下）

修改wxPython-4.1.0-cp37-cp37m-win_amd64.whl文件名字為wxPython-4.1.0-cp37-cp37m-win32.whl
在命令行窗口python的安裝目錄/Scripts下執行pip install wxPython-4.1.0-cp37-cp37m-win32.whl
如圖所示：
不容易啊，總算安裝成功了
