解决git push错误：failed to push some refs to git
一、错误信息
XXXXX MINGW64 /e/gitProjects/myDemoPro (master)
$ git push origin master
To [email protected]:XXXXX/myDemoPro.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to '[email protected]:zuiwangzuo/myDemoPro.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.
二、问题分析
先到github上看看远程repository下到底有啥东西，发现目标库是空的。
但是有一个README.md文件（本地代码中没有），而出现错误的原因是github中的README.md文件不在本地代码目录中。
也就是说我们需要先将远程代码库中的任何文件先pull到本地代码库中，才能push新的代码到github代码库中。
三、解决问题
1. 将远程代码库中的代码pull到本地代码库，并且执行合并merge：
$ git pull --rebase origin master
warning: no common commits
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 3 (delta 0), pack-reused 0
Unpacking objects: 100% (3/3), done.
From github.com:zuiwangzuo/myDemoPro
* branch master -> FETCH_HEAD
* [new branch] master -> origin/master
First, rewinding head to replay your work on top of it...
Applying: 提交初始代码。
2. 再次push代码：
$ git push origin master
Counting objects: 20, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (12/12), done.
Writing objects: 100% (20/20), 2.51 KiB | 0 bytes/s, done.

To [email protected]:zuiwangzuo/myDemoPro.git
8227f7c..aff8663 master -> master
我们看到本地代码已经成功的提交到远程代码中，至此问题解决。
