git推送报错“! [rejected] master -＞ master (fetch first)解决办法

git推送报错“! [rejected] master -> master (fetch first)"

今天上传git的时候出现了

To [e-mail]:yangzhi/hello.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to '[e-mail]:yangzhi/hello.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushin
hint: to the same ref. You may want to first merge the remote changes (e.g.
hint: 'git pull') before pushing again.

导致该错误的原因是我和同事在同一时间段上传了git（在同一项目下，而且他先于我上传）
解决办法：
先拉取项目，然后再推送
