DefinitelyTyped Typescript Definition不識別貓鼬的依賴關係

Question

我正在使用TypeScript，Angular 2和貓鼬。我使用NPM安裝貓鼬：

"dependencies": { 
    "@angular/common": "2.0.0-rc.6", 
    "@angular/compiler": "2.0.0-rc.6", 
    "@angular/core": "2.0.0-rc.6", 
    "@angular/forms": "2.0.0-rc.6", 
    "@angular/http": "2.0.0-rc.6", 
    "@angular/platform-browser": "2.0.0-rc.6", 
    "@angular/platform-browser-dynamic": "2.0.0-rc.6", 
    "@angular/router": "3.0.0-rc.2", 
    "@angular/upgrade": "2.0.0-rc.6", 
    "body-parser": "^1.15.2", 
    "bootstrap": "^3.3.6", 
    "core-js": "^2.4.1", 
    "express": "^4.13.4", 
    "jquery": "^3.1.0", 
    "mongoose": "^4.6.0", 
    "morgan": "^1.7.0", 
    "path": "^0.12.7", 
    "reflect-metadata": "^0.1.3", 
    "rxjs": "5.0.0-beta.11", 
    "systemjs": "0.19.27", 
    "typescript": "^2.0.0", 
    "typings": "^1.3.2", 
    "zone.js": "^0.6.17" 
    }, 
    "devDependencies": { 
    "jasmine-core": "^2.5.1", 
    "karma": "^1.2.0", 
    "karma-chrome-launcher": "^2.0.0", 
    "karma-cli": "^1.0.1", 
    "karma-firefox-launcher": "^1.0.0", 
    "karma-jasmine": "^1.0.2" 
    } 

當然，貓鼬會將mongodb作爲依賴項安裝。我然後使用命令typipngs install dt~mongoose --global --save.用來安裝貓鼬索引文件安裝貓鼬DefintielyTyped定義：

// Generated by typings

declare module "mongoose" { 
    import events = require('events'); 
    import mongodb = require('mongodb'); 
    import stream = require('stream'); 
    import mongoose = require('mongoose'); 

等等，等等。當我運行tsc，我得到以下錯誤：typings/globals/mongoose/index.d.ts(5,28): error TS2307: Cannot find module 'mongodb'。它不適合npm install mongodb --save，因爲它已經安裝了貓鼬。

解決此問題的正確方法是什麼？

Answer 1

它不是要求您安裝模塊，而是要求您安裝mongodb的類型。默認情況下，類型不會安裝依賴類型。所以你必須通過手動安裝每個依賴關係。

特別是對於貓鼬，你將需要類型mongodb,mpromise和mongoose-promise（我認爲這就是他們全部）。
