node.js - 模块内的 Webpack 未找到 Cheerio

Question

我正在使用scrape-it模块:https://github.com/IonicaBizau/scrape-it

我正在尝试将我的 js 与 webpack 捆绑在一起。但是，我遇到了这个错误:

ERROR in ./~/scrape-it/~/cheerio/index.js
Module not found: Error: Cannot resolve 'file' or 'directory' ./package in /Users/Spicycurryman/Desktop/Main/styell/node_modules/scrape-it/node_modules/cheerio
resolve file

完整堆栈跟踪:

我有点困惑为什么会发生这种情况，因为所有适当的模块都存在。 这是我的 webpack.config.js 文件，它可能是问题的根源。

var webpack = require('webpack');
var path = require('path');
var fs = require('fs');
var request = require('request');
var CaseSensitivePathsPlugin = require('case-sensitive-paths-webpack-plugin');


module.exports = {
    entry: "./main.js",
    output: {
        path: __dirname,
        filename: "bundle.js"
    },
    module: {
    loaders: [
      { test: /\.json$/, loader: 'json-loader' }
        ]
    },
    resolve: {
        extensions: ['', '.webpack.js', '.web.js', '.js']
    },
    node: {
        console: 'empty',
        fs: 'empty',
        net: 'empty',
        tls: 'empty'
    }
}

为什么会发生这种情况？如何解决这个问题？

Answer 1

我明白了。

我必须将'.json' 添加到resolve.extensions。

我现在收到了一个不相关的错误:
