git push报错

Question

之前在gitHub上弄好了SSH并成功推送过一次，今天推送的时候报错

$ git push origin master
To [e-mail]:ZhuYutao/learngit.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to '[e-mail]:ZhuYutao/learngit.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.

Answer 1

错误信息中有原因。
在你这次push之前，有其他人push到了服务器上。你本地不是最新的。
你需要先git pull一下，然后在push。

Answer 2

楼上是一个解决办法，还可以强制提交

Answer 3

在每次提交的时候还是git pull 再git push 这个是习惯吧 否则会出现上述情况
