pacman 的配置
编辑 /etc/pacman.d/mirrorlist.mingw32 ，在文件开头添加：
  Server = http://mirrors.ustc.edu.cn/msys2/REPOS/MINGW/i686
  Server = http://mirror.bit.edu.cn/msys2/REPOS/MINGW/i686
编辑 /etc/pacman.d/mirrorlist.mingw64 ，在文件开头添加：
  Server = http://mirrors.ustc.edu.cn/msys2/REPOS/MINGW/x86_64
  Server = http://mirror.bit.edu.cn/msys2/REPOS/MINGW/x86_64
编辑 /etc/pacman.d/mirrorlist.msys ，在文件开头添加：
  Server = http://mirrors.ustc.edu.cn/msys2/REPOS/MSYS2/$arch
  Server = http://mirror.bit.edu.cn/msys2/REPOS/MSYS2/$arch
然后执行 pacman -Sy 刷新软件包数据即可。
