Python相关

1.由于使用Python，首先安装管理包工具pip

<pre class="prettyprint prettyprinted" style="font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; margin: 10px 0px 0px; padding: 0px; font-family: ConfluenceInstalledFont, monospace; color: rgb(51, 51, 51); font-size: 14px; font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);">$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py # 下载安装脚本 </pre>

<pre class="prettyprint prettyprinted" style="font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; margin: 10px 0px 0px; padding: 0px; font-family: ConfluenceInstalledFont, monospace; color: rgb(51, 51, 51); font-size: 14px; font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);">$ sudo python get-pip.py # 运行安装脚本</pre>

2.Install uiautomator2

<pre style="font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; margin: 10px 0px 0px; padding: 0px; font-family: ConfluenceInstalledFont, monospace; color: rgb(51, 51, 51); font-size: 14px; font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);">pip install --upgrade --pre uiautomator2</pre>

<pre style="font-style: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; margin: 10px 0px 0px; padding: 0px; font-family: ConfluenceInstalledFont, monospace; color: rgb(51, 51, 51); font-size: 14px; font-variant-ligatures: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255);">pip install pillow</pre>

报错：

Consider using the --user option or check the permissions.

原因：权限问题。
