我有角度的应用程序，我想用 Heroku 部署它，我使用以下命令在本地构建了我的项目：
node --max_old_space_size=4096 node_modules/@angular/cli/bin/ng build
一切都很好。 我使用以下命令在本地运行我的项目：
node server.js
然后我尝试通过 heroku 部署该应用程序 - github 当我尝试部署分支时，我遇到了错误，这是错误的日志：

我该如何解决它？
LoginComponent 和 RegisterComponent 在两个模块(AuthentictionModule 和 AppModule(中声明。要解决此问题，您必须在其中一个模块中声明这些组件，而不是在两个模块中声明一个组件。之后，您可以在本地尝试ng build以检查是否存在其他错误。此外，如果您在 Heroku 上构建作为生产模式，您可以使用ng build --prod进行本地检查。
