关于如何将本地的仓库代码提交到github上

当我们在github上构建好自己的仓库的时候，我们可以使用下面的命令来进行提交

git init
git add .
git commit -m "first commit"
git remote add origin https://xxx.xxx.xxx
git push -u origin master

可能你会遇到下面的问题

$ git push -u origin master
得到下面的反馈，在github上有你没有文件，需要你先pull下来后再进行上传

To https://github.com/ruanjiayu/RabbitMQ.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/ruanjiayu/RabbitMQ.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.

那么我输入了下面的指令

$ git pull origin master
提示我两个分支没有任何的交际，不能在本地进行合并。


From https://github.com/ruanjiayu/RabbitMQ
 * branch            master     -> FETCH_HEAD
fatal: refusing to merge unrelated histories

解决的办法就是

 git pull -f origin master --allow-unrelated-histories

这样就可以把无关的分支合并了

注意上述出现问题的原因是，你的github上有文件，如新建的仓库有一个readme.md，但是本地仓库没有导致的
