将 master 分支推送到 origin 服务器时失败了：
$ git push origin master
fatal: 'origin' does not appear to be a git repository
fatal: Could not read from remote repository.Please make sure you have the correct access rights
and the repository exists.
解决方案：
$ git remote add origin http://gitlab.cloudadmin.cloud.csg.cn/d469b6ee-b772-4a56-9100-a48b3e9177e1/cangku0319.git
然后再输入：git push origin master 就可以提交了
$ git push -f origin master
