一个关于git push失败的解决方案

问题背景：在GitHub上创建了一个repositorie, 本地初始化并添加了远程仓库后，在GitHub上创建了一个README.md文件（注意不是从本地git push上去的），随后本地修改工程源码再次git push时，报错。。。。

To https://git.oschina.net/erchoc/laradock.git

 ! [rejected]        dev -> dev (fetch first)

error: failed to push some refs to 'https://git.oschina.net/erchoc/laradock.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.

解决方案：

# 先输入git pull
$ git pull

# 再git push
$ git push origin master
