Git首次push报错

$ git push -u origin master
To [email protected]:xxx/xxx.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to '[email protected]:xxx/xxx.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.

初始化git后push到github错误提示

原因：没有添加 readme.txt

解决方法：

方法1、在github的工程内，手动添加README.txt，本地分支内pull最新

方法2、在本地vim一个新的readme.txt文件，填入内容，commit后再次 push到github

附加：

也有可能是远程仓库 添加了新文件，本地不是最新的远程仓库版本号

需要先拉去 远程仓库到本地

git pull --rebase

or 

git pull  --rebase // 可以不用如果没有
