我现在拥有三连胜新手状态-Angular，Bootstrap和Heroku的新手。我希望没有启动VPS，而是希望建立一个引导仪表板并在诸如Heroku之类的PaaS平台上运行，但我一直遇到问题并陷入困境。
我尝试了以下2种方法，但均未成功： https://github.com/coreui/coreui-free-bootstrap-admin-template https://dashboardpack.com/theme-details/architectui-angular-7-dashboard-free/
我已经完成了一个干净的github存储库，按照Heroku的说明编辑了文件，但是无法运行仪表板。
我的Procfile具有：
web: npm run serve
它可以编译，但是当我运行时我得到： 应用程序错误 应用程序中发生错误，无法提供您的页面。如果您是应用程序所有者，请检查日志以获取详细信息。您可以使用以下命令从Heroku CLI执行此操作 heroku日志--tail
我在日志中看到的只是：
