当我在localhost上本地运行它时，ng build --aot --prod运行没有问题，但是当我在heroku上部署时，它不再识别组件的导入。它表示package.json中可能缺少依赖项，但是我按照本指南的建议添加了devDependencies的所有依赖项 https://itnext.io/how-to-deploy-angular-application-to-heroku-1d56e09c5147。
我查看并尝试了许多发现可以研究的解决方案，但到目前为止没有任何工作。我真的不知道从哪里开始调试此问题，将不胜感激
edit：放弃尝试修复它，所以我只是创建了一个新的Angular项目，并且只是在src上复制并更改了新的应用程序package.json，现在它可以了，所以我不知道问题出在哪里实在太沮丧了，无法解决。
