Question

我正在尝试将Typescript与tsd（尚未升级到typings），React和JSX一起使用......哦，我的！谈谈构建系统的复杂性......

当我使用.tsx时，我的gulp-typescript文件（Typescript + JSX）编译得很好（使用import * as React from 'react'）。但是，当我使用require语句时，我收到错误：

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

如果我输入错误并且旧的require和新import之间存在一些我还没有理解的差异，我不会感到惊讶，但我想我得到的特殊类型冲突错误很奇怪。

我理解导入如何更好地与全局tsd声明进行交互，为什么require语句会导致错误？

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" />
/// <reference path="react/react-addons-css-transition-group.d.ts" />

反应-global.d.ts

不要安装全球反应。我很高兴看到你已经使用了模块（更多https://github.com/basarat/typescript-book/blob/master/docs/tips/outFile.md）所以使用install react typings install dt~react --save将安装模块做出反应，然后import * as React from "react";

为什么要求（＆＃39;反应＆＃39;）导致＆＃34;导入声明冲突＆＃34;打字稿？
