github 不能推的其中一種狀況 甚至雲端是空的

To https://github.com/name/resp.git
 ! [rejected]        main -> main (non-fast-forward)
error: failed to push some refs to 'https://github.com/name/resp.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

若是有東西 可以先pull下來，因為可能本機是舊檔

git pull origin main

再

git push origin main

再不行 甚至雲端是空的

直接強推吧(不推薦)

git push -f origin main
