将 "require" 库导入 ReactJS 项目

Question

我正在学习 ReactJS 语言，现在我需要将 request 库添加到我的项目中。所以我通过 npm install 命令从 github.com/request/request 下载了库，现在我需要将这个库导入到我的项目中。

但是我什么时候会用：

import Request from 'request';

或

var request = require('request');

然后我无法构建我的应用程序（由于一些错误）。我不确定，如果我可以通过这种方式将第 3 方模块 （或如何调用） 导入 ReactJS。

你能帮我一点忙吗？

====包含错误====

在我的 .jsx 文件中我有：

import React from 'react';
var request = require('request');
import {Table, TableBody, TableFooter, TableHeader, TableHeaderColumn, TableRow, TableRowColumn} from 'material-ui/Table';
import TextField from 'material-ui/TextField';
import RaisedButton from 'material-ui/RaisedButton';
import FloatingActionButton from 'material-ui/FloatingActionButton';
import DialogWindow from '../components/DialogWindow.jsx'

import ContentAdd from 'material-ui/svg-icons/content/add';
import PlayArrow from 'material-ui/svg-icons/av/play-arrow';
import PlaylistAdd from 'material-ui/svg-icons/av/playlist-add';

如您所见，请求在第二行导入。当我尝试构建我的应用程序时，我会收到此错误：

看起来像是图书馆的一个已知问题。 https://github.com/request/request/issues/1529 中描述了一个修复程序（将 node 配置对象添加到您的 Webpack 配置）以使库在浏览器中工作。

但是，您可能需要考虑使用替代库，例如 isomorphic-fetch or axios。

将 "require" 库导入 ReactJS 项目

Import "require" library into ReactJS project

require

node.js

npm

reactjs
