问题描述：! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'https://gitee.com/码云仓库名'

hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
错误原因其实是我本地没有README.md这个文件，而远程仓库中有
git pull --rebase origin master
执行完后会发现本地已经有了 README.md 这个文件!
当时建仓库时有这个选项点了，哈哈。
现在想想是不是很好奇？？？
！！！记得对比才能发现问题！
然后上传
git push -u origin master
或点push.
然后登录码云，找到你上传的仓库，会在所在码云仓库上看到你上传的代码。
