Push to remote warehouse

git push -u origin master

The following error occurred

! [rejected]        master -> master (fetch first)
error: failed to push some refs to '[email protected]:qiyuebuku/WxRobot.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.

The solution is to connect the changes of the local warehouse to the main branch of the remote warehouse before pushing to the remote server

git pull origin master 

git push -u origin master //Push files from local repository to remote repository wen

Done!
