1. git add .

2. git commit -m 'XXX'

3. git push

提交push 报错：

$ git push origin master

Tohttps://gitee.com/xxx/******.git

! [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
