我在 heroku 上有一个 create-react-app。当我尝试将更改部署到生产时，它失败并给我以下错误：
Module not found: Error: Cannot resolve 'file' or 'directory' ./lib/ReactDOM in /tmp/build_a87ef5601c25702212bff26dba1f999c/node_modules/react-dom
但是，当我这样做时它是成功的npm run build。这是我的 package.json 文件：

我尝试删除 node_modules 文件并按照此处的建议重新安装，但我继续收到相同的错误。我已经使用 heroku 设置了 buildpack，并且上周能够成功部署该应用程序。任何帮助或建议将不胜感激。
