git报错You are not allowed to force push code to a protected branch on this project
当我们有时候回滚了代码，想强制push到远程仓库的时候，
git push origin --force
会报如下错误：
You are not allowed to force push code to a protected branch on this project
如果用的是gitlab版本库，这说明gitlab对仓库启用了保护，需要在仓库中设置一下：
"Settings" -> "Repository" -> scroll down to "Protected branches".
