解决Git push时error: failed to push some refs to...

今天git push origin master 报错：

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

原因是远程仓库中的文件和我们本地的仓库有差异，例如你的远程仓库有个文件Readme.md，但是本地仓库却没有，就可能会出现这种情况。

之所以出现这种情况，原因多种多样，例如你直接使用了github上传文件，或者像我一样，这次使用了另外一个系统推送了文件，导致了此问题的出现。解决办法显然有，把本地仓库删了再git clone一个，但是这种方法显然不可取….

解决办法：使用git pull 合并分支

git pull --rebase origin master

git pull命令用于从另一个存储库或本地分支获取并集成(整合)，取回远程主机某个分支的更新，再与本地的指定分支合并。
