body-parser.d.ts中的打字稿编译错误：找不到符号“缓冲区”

Question

I am getting the following compile errors in body-parser.d.ts when compiling my typescript file.

error TS2095: Could not find symbol 'Buffer'. error TS2094: The property 'RequestHandler' does not exist on value of type 'express'.

And I have the following lines in my app.ts file.

///<reference path='../Scripts/typings/node/node.d.ts'/>
///<reference path='../Scripts/typings/body-parser/body-parser.d.ts'/>

import express = require('express');
import bodyParser = require('body-parser');
import http = require('http');
import path = require('path');

Why am I getting the errors?

Make sure you have express.d.ts as it is required for body-parser.d.ts : https://github.com/borisyankov/DefinitelyTyped/blob/master/body-parser/body-parser.d.ts#L6

Very unlikely to be a bug in the Definitions as DefinitelyTyped is compiled to make sure that such errors don't make it to users like yourself.
