【问题描述】：

我运行了 webpack，并想使用 emailjs-imap-client。 可悲的是我无法让它工作...... 我总是收到以下错误：

这对我来说看起来很奇怪，因为它在尴尬的地方寻找模块。我的 npm 模块位于 /home/yatekii/Yatekii.github.io/react-hot-boilerplate/node_modules/。 例如，模块 emailjs-imap-formal-syntax 在这里：./node_modules/emailjs-imap-client/node_modules/emailjs-imap-handler/src/emailjs-imap-formal-syntax.js

如何让 node/webpack 找到模块？ :S

我在我的 webpack-config 中试过这个：

var path = require('path');
var webpack = require('webpack');

module.exports = {
  devtool: 'eval',
  entry: [
    'webpack-dev-server/client?http://localhost:3000',
    'webpack/hot/only-dev-server',
    './src/index'
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'bundle.js',
    publicPath: '/static/'
  },
  plugins: [
    new webpack.HotModuleReplacementPlugin()
  ],
  module: {
    loaders: [
      {
        test: 'emailjs-imap-client',
        loader: "imports?define=>false"
      },
      {
        test: 'emailjs-imap-client-imap',
        loader: 'imports?define=>false',
        include: 'emailjs-imap-client/src/emailjs-imap-client-imap.js')
      },
      {
        test: /\.js$/,
        loaders: ['react-hot', 'babel'],
        include: path.join(__dirname, 'src')
      },
    ]
  }
};

我刚刚收到错误消息：

var ImapClient = require('emailjs-imap-client');
var client = new ImapClient('mail.yatekii.ch', 143, {
        auth: {
                user: 'yatekii@yatekii.ch',
                pass: 'VERYSECRET'
        }
    }
)

有人可以帮助我吗？万分感谢！ 和平Yatekii

    【解决方案1】：

    看看我使用 emailjs 模块 + webpack 的例子：

    https://github.com/Axel186/emailjs-and-webpack-example

    在那里你可以找到使用 emailjs-imap-client 的工作客户端示例。

    无论如何，这里是 webpack 配置文件的一部分：

      ...
  module: {
    loaders: [{
      test: /\.js$/,
      exclude: /(node_modules|forge\.js)/,
      loader: 'babel-loader',
      query: {
        compact: true,
        presets: ['es2015']
      }
    }]
  },
  alias: {
    forge: 'forge.js'
  },
  resolve: {
    root: [
      // path.resolve('./src/app'),
      path.resolve('./src/'),
      path.resolve('./node_modules/emailjs-imap-client/src/'),
      path.resolve('./node_modules/emailjs-imap-handler/src/'),
      path.resolve('./node_modules/emailjs-tcp-socket/src/'),
      path.resolve('./node_modules/emailjs-smtp-client/src/'),
      path.resolve('./node_modules/emailjs-stringencoding/src/'),
    ]
  },
  ...
