无法解决此问题：
app.component.ts
import { AngularFire,AuthProviders,AuthMethods } from 'angularfire2';
/angularfire2/index has no exported member 'AngularFire',/angularfire2/index has no exported member 'AuthProviders',/angularfire2/index has no exported member 'AuthMethods '
但是在app.module.ts中
import { AngularFireModule } from 'angularfire2';
工作正常,我可以初始化应用程序
的package.json
"angularfire2": "^4.0.0-rc.0","core-js": "^2.4.1","firebase": "^3.9.0",...
"devDependencies": {...
"ts-node": "~2.0.0","tslint": "~4.5.0","typescript": "~2.2.0"
由于您使用的是angularfire2@4.0.0,因此不再导出AngularFire.相反,您将使用它如下：
原文链接：https://www.f2er.com/angularjs/143488.html// import AngularFireAuthModule at NgModule
import { AngularFireAuthModule } from 'angularfire2/auth';
import { AngularFireAuth } from 'angularfire2/auth';
// inject
construstor(afa: AngularFireAuth) {
afa.auth.signInWithPopup()
}
