git上传代码到code.csdn.net出错

用git push代码到csdn code的时候出现错误
error:failed to push some refs to …
Dealing with “non-fast-forward” errors
From time to time you may encounter this error while pushing:
$ git push origin master
To ../remote/
! [rejected] master -> master (non-fast forward)
error: failed to push some refs to ‘../remote/’
To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes before pushing again. See the ‘non-fast forward’
section of ‘git push –help’ for details.

找了很多网上的答案都是
先把git的东西fetch到你本地然后merge后再push

$ git fetch
$ git merge

和

$ git pull 

都是错的，正确的是

$ git pull git@code.csdn.net:你的名字……

一定要加 git@这
然后push

$ git push -u 名字 master

master代表主分支
