Typescript找不到名稱'Firebase'

嘗試構建包含angularfire2和firebase的項目時，出現打字稿錯誤。下面是包：Typescript找不到名稱'Firebase'

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

，這裏是錯誤：

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

如果我打開node_modules database.d.ts，沒有對「火力地堡」這樣我就可以明白爲什麼進口這將失敗..它期望從哪裏獲得'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>; 
}

我不知道爲什麼它甚至檢查node_modules分型..它的一部分，我排除tsconfig.json

{ 
    "compilerOptions": { 
    "target": "es5", 
    "module": "commonjs", 
    "declaration": false, 
    "removeComments": true, 
    "noLib": false, 
    "emitDecoratorMetadata": true, 
    "experimentalDecorators": true, 
    "sourceMap": true, 
    "pretty": true, 
    "allowUnreachableCode": false, 
    "allowUnusedLabels": false, 
    "noImplicitAny": true, 
    "noImplicitReturns": true, 
    "noImplicitUseStrict": false, 
    "noFallthroughCasesInSwitch": true 
    }, 
    "exclude": [ 
    "node_modules", 
    "dist", 
    "typings/browser.d.ts", 
    "typings/browser", 
    "src" 
    ], 
    "compileOnSave": false 
}
