我在Vercel上为我已经部署的React项目推送了一个新的更新后，收到了这个错误。在尝试了几种方法来解决它，但都被证明是徒劳的之后，我决定删除部署并完全重新部署它，但我仍然遇到了同样的问题。

我尝试过这些命令，它对我很有效：
1-git rm-r-cached从git存储库的索引中删除所有文件和目录，但将它们保留在本地文件系统中。
2-git add--all将所有文件和目录，包括未跟踪的文件，添加到git存储库的索引中。
3位提交-a-m"；版本控制未跟踪的文件">创建一个新的提交，其中包括索引中的所有更改，包括修改和删除。提交消息是"；版本控制未跟踪的文件"；。
4位推送源主机将本地提交推送到名为"的远程存储库；原点"；而分支"；"大师"；。将本地更改与远程存储库同步。
