我尝试开始使用TypeScriptReact。由于 React 是用 JavaScript 编写的,所以我使用npm安装它

npm install --save react

我需要 React 的类型定义。所以我尝试了

$ typings install react --save
typings ERR! message Unable to find "react" ("npm") in the registry. Did you want to try searching another source? Also, if you want contribute these typings, please help us: https://github.com/typings/registry
typings ERR! caused by https://api.typings.org/entries/npm/react/versions/latest responded with 404, expected it to equal 200

我跑过去typings search react发现

NAME   SOURCE  HOMEPAGE                          DESCRIPTION  VERSIONS  UPDATED
react  dt      http://facebook.github.io/react/               2         2016-05-26T13:46:01.000Z

因此,我明确指定了来源

$ typings i dt~react --save
typings ERR! message Attempted to compile "react" as an external module, but it looks like a global module.

我可以全局安装 React

typings install dt~react --save --global

但是当我尝试导入 React 时, Atom仍然抱怨Cannot find module 'react'

import React from 'react'

如何安装 React 或配置 TypeScript 以便可以在 TypeScript 中导入 React?

React 库没有默认导出。因此,当您要求它时import React,它会在该库中查找默认导出。不幸的是,它不存在。相反,以这种方式导入整个内容和命名空间:

import * as React from 'react';
