/ angularfire2/index没有导出成员'AngularFire'

Question

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"

Answer 1

由于您使用的是angularfire2@4.0.0+,因此不再AngularFire导出.相反,您将使用它如下:

// import AngularFireAuthModule at NgModule
import { AngularFireAuthModule } from 'angularfire2/auth';


import { AngularFireAuth } from 'angularfire2/auth';
// inject 
construstor(afa: AngularFireAuth) {
  afa.auth.signInWithPopup()
}
