Javascript require（）函数给出了ReferenceError：require未定义 [英] Javascript require() function giving ReferenceError: require is not defined

问题描述

基本上，我使用javascript从Google Play商店中抓取数据：

Basically, I am using javascript to scrape data from Google Play store using:

1-Request

1-Request

2-Cheerios

2-Cheerios

3-QueryString

3-QueryString

我使用了Github的Google Market API，其中使用require如下：

I used Google Market API from Github which uses require as following:

var request   = require('request');
var cheerio   = require('cheerio');
var qs      = require('querystring');

但我收到以下信息

ReferenceError：require未定义...

ReferenceError: require is not defined ...

所以，我没有javascript中的要求，这对我来说是新的，或者这是不寻常的。

So, I don't have require in javascript which is either new for me or this is something out of the ordinary.

推荐答案

RequireJS是一个JavaScript文件和模块加载器。它针对
浏览器内使用进行了优化，但它可以在其他JavaScript环境中使用，例如Rhino和Node。使用像RequireJS这样的模块化脚本加载器将
提高代码的速度和质量。

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.
