Git使用命令“git push -u origin master”报错

错误

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.

出错原因

hint中显示“remote包含本地没有的文件”，提示你在执行push先把使用pull它integrate(合并)

解决方法

git pull --rebase origin master 合并项目
git push -u origin master 上传
