我收到错误，并且使用angularfire for firebase也没有数据进入Angular和离子应用程序 .
package.json：
"dependencies": {
"@angular/common": "5.0.3",
"@angular/compiler": "5.0.3",
"@angular/compiler-cli": "5.0.3",
"@angular/core": "5.0.3",
"@angular/forms": "5.0.3",
"@angular/http": "5.0.3",
"@angular/platform-browser": "5.0.3",
"@angular/platform-browser-dynamic": "5.0.3",
"@ionic-native/core": "4.4.0",
"@ionic-native/splash-screen": "4.4.0",
"@ionic-native/status-bar": "4.4.0",
"@ionic/pro": "1.0.16",
"@ionic/storage": "2.1.3",
"angularfire2": "^5.0.0-rc.1",
"firebase": "^4.4.0",

"ionicons": "3.0.0",
"rxjs": "5.5.2",
"sw-toolbox": "3.6.0",
"zone.js": "0.8.18"
},
火力服务：
constructor(public afDB: AngularFireDatabase) {
console.log('Hello FireBaseServicesProvider Provider');
}
getStockUserList(){
// let getData = this.afDB.list().
return this.afDB.list('stock/').valueChanges();
// this.afDB.list('stock/');
}
在page.ts文件中：
stockList: Observable<any>;
this.stockList = this.fbService.getStockUserList();
在HTML中：
<ul>
<li *ngFor="let item of stockList | async">
{{ item.age }}
</li>
</ul>
在firebase库存清单中，使用唯一键具有名称和年龄 . 添加正在工作，但数据从firebase有问题，并且还显示“ngFor仅用于数组元素”和
typescript error
Cannot find type definition file for 'firebase'.

回到firebase 4.8.0：
在CLI中，项目路径类型为：
npm uninstall firebase然后一旦鱼卸载，请输入：npm cache clear然后输入：
npm install firebase@^4.8.0finally：删除
package.json中依赖项中的"firebase": "^5.0.0-rc.1"并输入"firebase": "4.8.0"
