Typescript找不到名称'；Firebase'；

在尝试构建包含angularfire2和firebase的项目时，我会遇到类型脚本错误。以下是包裹：

"angularfire2": "^2.0.0-beta.0",
"firebase": "^2.4.2",

以下是错误：

[10:58:34] Finished 'build.html_css' after 4.51 s

如果我在node_模块中打开database.d.ts，则“Firebase”没有导入，因此我可以了解此操作失败的原因。。它希望从哪里获得“Firebase”

import { FirebaseListObservable } from '../utils/firebase_list_observable';
import { FirebaseObjectObservable } from '../utils/firebase_object_observable';
import { FirebaseListFactoryOpts } from '../utils/firebase_list_factory';
import { FirebaseObjectFactoryOpts } from '../utils/firebase_object_factory';
export declare class FirebaseDatabase {
    private fbUrl;
    constructor(fbUrl: string);
    list(urlOrRef: string | Firebase, opts?: FirebaseListFactoryOpts): FirebaseListObservable<any[]>;
    object(urlOrRef: string | Firebase, opts?: FirebaseObjectFactoryOpts): FirebaseObjectObservable<any>;
}

将其添加到.ts文件==>从“angularfire2”导入{AngularFire，FirebaseListObservable}

将其添加到.ts您的文件==>从“angularfire2”导入{AngularFire，FirebaseListObservable}
