git 无法push远程仓库 Note about fast-forwards 问题解决

  git push 远程仓库时，出现以下类似错误，'Note about fast-forwards' in 'git push --help' for details.

To https://github.com/SeshinWei/django.git
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/SeshinWei/django.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

错误：non-fast-forward
远程仓库：origin
远程分支：master
本地分支：master

完整报错代码可能是这样的：

There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull  

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=origin/ master

原因是没有指定本地 master 分支和远程 origin/master 的连接，这里根据提示：

git branch --set-upstream-to=origin/master master

 

 解决方案：因为远程仓库新建时，有LIENCE，由于本地仓库和远程仓库有不同的开始点，也就是两个仓库没有共同的commit出现，无法提交，此时我们需要allow-unrelated-histories。也就是我们的 pull 命令改为下面这样的：

git pull origin master --allow-unrelated-histories

如果设置了默认分支，可以这样写：

git pull --allow-unrelated-histories

然后 git push 就可以了。
