为什么 ng serve 在 angular 中会抛出错误？

Question

使用ng serve运行时出现以下错误。

ERROR in Error: Error encountered resolving symbol values statically. Calling function 'OpaqueToken', function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol FirebaseUserConfig in C:/Users/mohammad/Desktop/My Programming World/My SPA/My Angualr/pinterest/node_modules/angularfire2/tokens.d.ts, resolving symbol AngularFireModule.initializeApp in C:/Users/mohammad/Desktop/My Programming World/My SPA/My Angualr/pinterest/node_modules/angularfire2/angularfire2.d.ts, resolving symbol AppModule in C:/Users/mohammad/Desktop/My Programming World/My SPA/My Angualr/pinterest/src/app/app.module.ts, resolving symbol AppModule in C:/Users/mohammad/Desktop/My Programming World/My SPA/My Angualr/pinterest/src/app/app.module.ts

我厌倦了删除 firebase Angular 但没有运气

项目来自https://github.com/aviabird/pinterest/issues有什么原因吗？

Answer 1

ng serve显示错误不会导致

如错误消息中所述，错误来自OpaqueToken 。 ng server只是在发生错误时显示错误消息。

错误：

不支持调用 function 'OpaqueToken'、function 调用。 Consider replacing the function or lambda with a reference to an exported function, resolving symbol FirebaseUserConfig in C:/Users/mohammad/Desktop/My Programming World/My SPA/My Angualr/pinterest/node_modules/angularfire2/tokens.d.ts, resolving符号 AngularFireModule.initializeApp 在
