error: failed to push some refs to 'gitee.com:lemon_guess/test.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.是不是在不同的机器上上做了提交？？
远程分支上存在本地分支中不存在的提交，往往是多人协作开发过程中遇到的问题，可以先fetch再merge，也就是pull，把远程分支上的提交合并到本地分支之后再push。
如果你确定远程分支上那些提交都不需要了，那么直接git push origin master -f，强行让本地分支覆盖远程分支。。。
