问题描述：安装离线proton-cs的时候，安装脚本默认支持是python2，在python3环境下安装会有部分不兼容。
解决方法：根据本问题的步骤进行操作即可解决。
1.先试用命令 ls 查看proton安装包，我们将安装脚本记为 installScript 。再使用 rm -f installScript 删除原安装包当中的脚本。
2.使用命令 vi installScript，创建新的安装脚本
3.按键盘a字母键，使得操作变为插入模式。
4.粘贴如下命令到文件当中。
#!/usr/bin/env python
# -*- coding:utf-8 -*-

5.按键盘的 ESC 退出插入模式，保存修改。如下图。保存完成之后，再使用原安装方式安装即可。
