这篇文章讲得挺清楚的，但是在上传的时候出现了问题
1 ! [rejected] master -> master (fetch first) 2 error: failed to push some refs to ‘https://github.com/thy00/e-shop.git‘ 3 hint: Updates were rejected because the remote contains work that you do 4 hint: not have locally. This is usually caused by another repository pushing 5 hint: to the same ref. You may want to first integrate the remote changes 6 hint: (e.g., ‘git pull ...‘) before pushing again. 7 hint: See the ‘Note about fast-forwards‘ in ‘git push --help‘ for details.
