# 处理非快进错误

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。

如果其他人已推送到与您相同的分支，Git 将无法推送您的更改：

```shell
$ git push origin main
> To https://HOSTNAME/USERNAME/REPOSITORY.git
>  ! [rejected]        main -> main (non-fast-forward)
> error: failed to push some refs to 'https://HOSTNAME/USERNAME/REPOSITORY.git'
> 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.
```

可以通过[提取和合并](/zh/enterprise-server@3.22/get-started/using-git/getting-changes-from-a-remote-repository)远程分支上所做的更改以及本地所做的更改来解决此问题：

```shell
$ 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：

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