错误：
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://gitee.com/caoyujing0816/cyjs---python-repository.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.
错误原因：
本地仓库和远程仓库文件不一致导致的
解决方法一：
创建一个新的空白仓库
底下三个方框都不要勾选，创建出来的就是空白仓库，否则仓库里有东西，导致本地与远端不同步无法上传
解决方法二：
执行git pull，然后再执行push就可以了，把远端仓库先同步到本地
git pull origin master
