$ git push -u origin master 推送到远程库出错
1、错误描述：
出错场景描述：
github上创建远程仓库的时候选择添加README.md文件，
git bash连接远程库，然后执行push操作，出现下面的问题
$ git push -u origin master
To github.com:XXXX/DesignPatterns.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'git@github.com:XXXX/DesignPatterns.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.
2、问题分析：
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。
3、解决方法：
（1）可以通过如下命令进行代码合并【注：pull=fetch+merge】
git pull --rebase origin master
（2）再执行语句：
git push -u origin master
即可完成代码上传到github。
去github上即可看到上传的项目
