1、不能直接使用win+r運行cmd並使用pip，必須點擊開始->windows系統->命令提示符，右鍵->以管理員身份運行

2、運行pip install pyautogui後提示You are using pip version 10.0.1, however version 19.0.1 is available.

這個是pip版本低了，根據提示運行python -m pip install --upgrade pip即可。

3、繼續運行pip install pyautogui出現錯誤：

這個錯誤是安裝pyautogui過程中遇到的一個核心錯誤，是安裝PyGetWindow過程中出現的，網上搜了一通，最後試了各種方法，就是降低PyGetWindow版本，默認安裝的PyAutoGUI-0.9.41，依賴的是PyGetWindow-0.0.4，就是這個PyGetWindow-0.0.4導致了上述問題，於是網上大神說降低PyGetWindow版本，運行pip install PyGetWindow==0.0.1後安裝PyGetWindow成功，然後再運行pip install pyautogui。
