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：
Thereisno tracking informationforthe current branch.Please specify which branch you want to mergewith.See git-pull(1)fordetails. git pull If you wish to set tracking informationforthis branch you can do sowith: 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。
