npm install socket.io --save

我有以下错误：

错误TS2307：找不到模块’socket.io-client’

进口

import * as io from 'socket.io-client';

systemjs.config.js

var map = {
    'socket.io-client': 'node_modules/socket.io-client/socket.io.js'
}

var packages = {
    'socket.io-client': { main: 'socket.io',format: 'cjs',defaultExtension: 'js' }
}

的package.json

"dependencies": {
    "socket.io": "^1.4.8"
}

typings.d.ts

/// <reference path="../socket.io-client/socket.io.js" />

declare module 'socket.io-client' {
  var e: any;
  export = e;
}

socket.io-client(目录)
– socket.io.js
– typings.d.ts
