1、在命令窗口中使用命令： pip install uiautomator2 时报 pip 版本过低，需要先升级 pip 版本，理论上会按照提示进行升级 pip 操作，但执行升级命令时到最后却还是报错，仍提示 pip 版本过低
解决办法：
直接先在命令窗口中执行命令： python -m pip install --upgrade pip setuptools wheel 待提示成功安装即可
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
此时再安装 uiautomator2 即可成功（都不需要升级 pip 版本号）
