嗨，我是一名尝试在 Heroku 上部署应用程序的初学者。我之前已经成功部署了一个应用程序，但由于某种原因，这次没有任何效果。我已经彻底遵循了这个博客的步骤： https ://medium.com/@hellotunmbi/how-to-deploy-angular-application-to-heroku-1d56e09c5147
我在最新版本的角度和节点上：
“@angular/cli”：“^6.0.1”，“@angular/compiler-cli”：“^6.0.1”，“node”：“10.1.0” ，“npm”：“6.0.0”
下面是我的构建日志和我的 package.json 文件供参考。没有错误，但应用程序在部署后无法工作:(请帮助！！

package.json 文件：（我必须使用 ng build --aot 而不是 ng build --aot -prod 因为后者在构建日志中给我一个错误说 > ng build --aot -prod Unknown option: '-p '。这在我以前的应用程序中对我有用。）
