1、在命令窗口中使用命令： pip install uiautomator2 時報 pip 版本過低，需要先升級 pip 版本，理論上會按照提示進行升級 pip 操作，但執行升級命令時到最后卻還是報錯，仍提示 pip 版本過低
解決辦法：
直接先在命令窗口中執行命令： python -m pip install --upgrade pip setuptools wheel 待提示成功安裝即可
1 Installing collected packages: setuptools, wheel 2 Found existing installation: setuptools 28.8.0 3 Uninstalling setuptools-28.8.0: 4 Successfully uninstalled setuptools-28.8.0 5 Successfully installed setuptools-40.0.0 wheel-0.31.1
此時再安裝 uiautomator2 即可成功（都不需要升級 pip 版本號）
