我是Ionic2的新手,并且是第一次使用firebase。在尝试使用上述两个示例登录应用程序时,我收到了编译错误
TypeScript错误:
TypeScript错误: /ionic/devdactic-firebase22/node_modules/angularfire2/database/database.d.ts(9,29): 错误TS2503:找不到命名空间' firebase'。 TypeScript错误: /ionic/devdactic-firebase22/node_modules/angularfire2/database/database.d.ts(10,31): 错误TS2503:找不到命名空间' firebase'。 TypeScript错误: /ionic/devdactic-firebase22/node_modules/angularfire2/providers/auth.d.ts(15,40): 错误TS2503:找不到命名空间' firebase'。 TypeScript错误: /ionic/devdactic-firebase22/node_modules/angularfire2/providers/auth.d.ts(16,52): 错误TS2503:找不到命名空间' firebase'。打字稿 错误:/ionic/devdactic-firebase22/node_modules/angularfire2/providers/auth.d.ts(16,92): 错误TS2503:无法找到命名空间' firebase'。
我尝试过使用AngularFire的安装指南:https://github.com/angular/angularfire2/blob/master/docs/1-install-and-setup.md。
还尝试在我的app.ts中导入firebase
从' firebase';
导入*作为firebase
仍然无法找到任何解决方案。可能是什么原因以及如何解决?
我正在使用angularfire2@^2.0.0-beta.2 和firebase@^2.4.2。
app.ts
import {Component} from '@angular/core';
import {Platform, ionicBootstrap} from 'ionic-angular';
import {StatusBar} from 'ionic-native';
import {LoginPage} from './pages/login/login';
import * as firebase from 'firebase';
import {FIREBASE_PROVIDERS,
defaultFirebase,
AngularFire,
AuthMethods,
AuthProviders,
firebaseAuthConfig} from 'angularfire2';
@Component({
template: '<ion-nav [root]="rootPage"></ion-nav>',
providers: [
FIREBASE_PROVIDERS,
// defaultFirebase('https://loginapp-a08a6.firebaseio.com/'),
firebaseAuthConfig({
provider: AuthProviders.Password,
method: AuthMethods.Password
})
]
})
export class MyApp {
rootPage: any = LoginPage;
constructor(platform: Platform) {
platform.ready().then(() => {
StatusBar.styleDefault();
});
var config = {
apiKey: "AIzaSyBU2Vqq7AjN4rlMWjyKBbXo2RVJXAR4TeM",
authDomain: "loginapp-a08a6.firebaseapp.com",
databaseURL: "https://loginapp-a08a6.firebaseio.com",
storageBucket: "loginapp-a08a6.appspot.com",
};
firebase.initializeApp(config);
}
}
ionicBootstrap(MyApp);
login.ts:
import {Component} from '@angular/core';
import {NavController, AlertController, LoadingController} from 'ionic-angular';
import {FirebaseAuth} from 'angularfire2';
import {HomePage} from '../home/home';
@Component({
templateUrl: 'build/pages/login/login.html',
})
export class LoginPage {
// public loading: Loading;
constructor(public nav: NavController,
public auth: FirebaseAuth,
private alertCtrl:AlertController,
private loadingCtrl:LoadingController) {}
public registerUser(credentials) {
this.showLoading()
this.auth.createUser(credentials).then((authData) => {
let prompt = this.alertCtrl.create({
title: 'Success',
subTitle: 'Your new Account was created!',
buttons: ['OK']
});
prompt.present();
}).catch((error) => {
this.showError(error);
});
}
public login(credentials) {
this.showLoading()
this.auth.login(credentials).then((authData) => {
this.nav.setRoot(HomePage);
}).catch((error) => {
this.showError(error);
});
}
showLoading() {
var loader = this.loadingCtrl.create({
content: 'Please wait...',
duration:3000
});
loader.present();
}
showError(text) {
let alert = this.alertCtrl.create({
title: 'Fail',
subTitle: text,
buttons: ['OK']
});
alert.present();
}
}

在 compilerSettings 下的 tsconfig 中,添加属性&#34; types&#34;并指定&#34; firebase&#34;作为一种类型:
{
"compilerOptions": {
"allowSyntheticDefaultImports": true,
"declaration": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": [
"dom",
"es2015"
],
"module": "es2015",
"moduleResolution": "node",
"target": "es5",
"types": [
"firebase"
]
},
"exclude": [
"node_modules"
],
"compileOnSave": false,
"atom": {
"rewriteTsconfig": false
}
}

有各种各样的答案可以解决这类问题。对我有用的是:
您可以直接在typings.json中引用angularfire2节点包中包含的Firebase 3 typings文件。 运行:
typings install file:node_modules/angularfire2/firebase3.d.ts --save --global
typings install
这会将打字文件放在typings/
目录中。
