为什么 require('react') 导致 "Import declaration conflicts" 与打字稿？

Question

我正在尝试将 Typescript 与 tsd (haven't upgraded to typings 一起使用）、React 和 JSX 一起使用……天啊！谈论构建系统的复杂性...

当我使用 import * as React from 'react' 时，我的 .tsx 文件（Typescript + JSX）编译正常（使用 gulp-typescript）。但是，当我使用 require 语句时出现错误：

./typings/react/react-global.d.ts(17,1): error TS2440: Import declaration conflicts 
with local declaration of 'React'

如果我只是导入错误，我不会感到惊讶，旧的 require 和新的 import 之间有一些我还没有弄清楚的区别，但我认为特别的我得到的类型冲突错误很奇怪。

只是为了更好地理解导入如何与全局 tsd 声明交互，为什么 require 语句会在此处导致错误？

这是我的 index.tsx:

/// <reference path="../typings/tsd.d.ts" />

const config = require('../config')
const express = require('express')
const reactDomServer = require('react-dom/server')
const app = express()

// THIS WORKS
import * as React from 'react'

// THIS DOES NOT
//const React = require('react')

app.get('/', (req, res) => {
  const element = <h1>Hello Denver!</h1>
  res.send(reactDomServer.renderToString(element))
})

const server = app.listen(process.env.port || config.port, () =>
  console.log(`Server listening on port ${server.address().port}!`)
)

这是我的 ../typings/tsd.d.ts:

/// <reference path="react-router/history.d.ts" />
/// <reference path="react-router/react-router.d.ts" />
/// <reference path="react/react-addons-create-fragment.d.ts" />

react-global.d.ts

不要全局安装 React。我很高兴看到你已经在使用模块（更多 https://github.com/basarat/typescript-book/blob/master/docs/tips/outFile.md）所以使用 install react as typings install dt~react --save 这将安装模块 react 然后你可以 import * as React from "react";

Why does require('react') cause "Import declaration conflicts" with typescript?

javascript

jsx

typescript

reactjs

tsd
