错误描述：
$ git push -u origin master To github.839022478/test.git ! [rejected] master -> master (fetch first) error: failed to push some refs to 'git@github.com:839022478/test.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.
在使用git 对源代码进行push到gitHub时可能会出错
出现错误的主要原因是github中的README.md文件不在本地代码目录中
可以通过如下命令进行代码合并：git pull --rebase origin master
执行上面代码后可以看到本地代码库中多了README.md文件
此时再执行语句 git push 即可完成代码上传到github
