[git 报错：error: failed to push some refs to 'https://gitee.com/xxx/******.git'（已解决）]
提交push 报错：

! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://gitee.com/xxx/******.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
这是因为远程库里面有个文件，但是本地没有这个文件，完全提交上去会覆盖之前的文件（通常是因为远程库自动生成了一个REMAND.MD的文件原因，但是本地没有add到这个文件）
我们直接强制push 下就可以了：
$ git push -u origin master -f
