在推送本地上 GitHub 跳出以下錯誤
$ git push -u origin master
To https://github.com/abc/docker-git-lab.git
! [rejected] master -> master (fetch first)
error: failed to push some refs to 'https://github.com/abc/docker-git-lab.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.
滿低級問題，原因大概是我在 GitHub 建 repository 時，勾了產出 README.md
就先把遠端合併回來再推上去，或強制把本地推上去
合併回來
$ git pull -r
推上去
$ git push -u origin master
或
$ git push -f參考來源： 另一種合併方式（使用 rebase）、【狀況題】怎麼有時候推不上去…
另外 Gitlab 分支保護設定也會影響到無法推上去，需要推到其他分支再發 Merga Request 合併進去
