有时,Git 无法在不丢失提交的情况下对远程仓库进行更改。 发生此情况时,推送会被拒绝。

如果其他人已推送与您相同的分支,Git 将无法推送您的更改:

$ git push origin main
> To
>  ! [rejected]        main -> main (non-fast-forward)
> error: failed to push some refs to ''
> To prevent you from losing history, non-fast-forward updates were rejected
> Merge the remote changes (e.g. 'git pull') before pushing again.  See the
> 'Note about fast-forwards' section of 'git push --help' for details.


$ git fetch origin
# Fetches updates made to an online repository
$ git merge origin YOUR_BRANCH_NAME
# Merges updates made online with your local work

或者,只需使用 git pull 一次执行这两个命令:

$ git pull origin YOUR_BRANCH_NAME
# Grabs online updates and merges them with your local work
