提取码：QAZW
提取之后放到D盘一个位置，不要删除！！！
点击方式2，Windows 系统，按照下面目录进入scripts目录，点击运行 install-current-user.vbs 脚本，为当前用户安装po jie补丁。
下面这个是Mac/Linux的，网上百度的，因为我没有这个电脑，大家可以自行试一下。
Mac/Linux 系统，进入到 scripts 目录下， 执行 sh 命令运行 install.sh 脚本安装，执行命令如下:
sh install.sh
PS: install-all-users.vbs 为系统所有用户安装，不太推荐。unistall-*前缀的是卸载补丁脚本。
运行之后第一个弹窗如下，点确定：
第二个弹窗如下：
点击确定即可。
到此，补丁安装成功。
