[英]Angular 4 with AngularFire2

原文 2017-04-10 22:10:32 3 1 angular/ firebase/ angularfire2

I am attempting to setup a new site in Angular 4. I want to use Firebase as a database backend. 我正在尝试在Angular 4中设置一个新站点。我想使用Firebase作为数据库后端。

I am using the install guide found here: https://github.com/angular/angularfire2/blob/master/docs/1-install-and-setup.md 我正在使用此处的安装指南： https ： //github.com/angular/angularfire2/blob/master/docs/1-install-and-setup.md

However, when I execute ng serve --open I am getting this error: 但是，当我执行ng serve --open我收到此错误：

ERROR in Error encountered resolving symbol values statically. ERROR in Error遇到静态解析符号值。 Calling function 'OpaqueToken', function calls are not supported. 调用函数'OpaqueToken'，不支持函数调用。 Consider replacing the function or lambda with a reference to an exported function, resolving symbol FirebaseUserConfig in C:/Source/node_modules/angularfire2/tokens.d.ts, resolving symbol AngularFireModule.initializeApp in C:/Source/node_modules/angularfire2/angularfire2.d.ts, resolving symbol AppModule in C:/Source/src/app/app.module.ts, resolving symbol AppModule in C:/Source/src/app/app.module.ts 考虑使用对导出函数的引用替换函数或lambda，在C：/Source/node_modules/angularfire2/tokens.d.ts中解析符号FirebaseUserConfig，在C：/ Source / node_modules / angularfire2 / angularfire2中解析符号AngularFireModule.initializeApp。 d.ts，在C：/Source/src/app/app.module.ts中解析符号AppModule，在C：/Source/src/app/app.module.ts中解析符号AppModule

As I am rather a novice with Angular, I am not sure how to resolve this error. 因为我是Angular的新手，我不知道如何解决这个错误。
