我已经部署了一个我正在工作的网站，它是Heroku的Reactjs Express应用程序。它已经部署了3周。但在最近对应用程序进行了一些更改后，我无法将代码推送到heroku。我在推送时遇到错误。

一段时间以来，我一直在努力寻找解决方案。上面提到的一些解决方案对我不起作用。有人能帮我解决这个问题吗？
我也遇到了类似的问题。这是解决方案。
- 在本地，运行以下命令
yarn set version berry
- 在.gitignore中激活零安装
.yarn/*
!.yarn/cache
!.yarn/releases
!.yarn/plugins
!.yarn/sdks
!.yarn/versions
或停用零安装
.pnp.*
.yarn/*
!.yarn/patches
!.yarn/plugins
!.yarn/releases
!.yarn/sdks
!.yarn/versions
yarn install并应用安装- 将所有更改提交给git-regitory
git push heroku main
