我有一个Angular 8应用程序，使用npm包Angular Firebase（https://github.com/angular/angularfire2），当我使用Angular CLI命令构建应用程序并将其ng build --prod部署到主机时，出现以下Chrome浏览器控制台错误：

TypeError: Object(...)(...).auth is not a function

如果我改用命令构建，ng build --prod --optimization=false则不会发生错误。

Angular CLI ng build选项optimization设置为true的情况导致AngularFire2 npm软件包错误。

我不确定如何进一步调试此问题。这是我的package.json文件：
