解决error: failed to push some refs to 'xxxx'

今天将项目修改了一部分，然后用 git push origin master 向远程仓库推送的时候报如下错误：

error: failed to push some refs to 'https://github.com/ZJyoung1997/JZShop.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。 我的就是远程仓库中有Readme. md文件，而本地仓库中没有该文件造成的。还有就是因为平时在协会中，用协会电脑开发，回到寝室后又会用自己的电脑开发，这可能也是导致这种问题的原因。这种情况有解决办法，就是将本地仓库直接干掉，然后重新从远程clone一个，但是这样显然太麻烦了，可以用合并分支的方法

解决办法：

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。

fatal: 'master' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

用 git pull origin master --allow-unrelated-histories 解决
