的WebPack 2例外 - 未捕獲的ReferenceError：我使用的WebPack 2，聞webpackJsonp沒有定義

Question

我執行

除外的WebPack-dev的服務器我在瀏覽器中得到：「未捕獲的ReferenceError：未定義webpackJsonp 「。

當我嘗試創建供應商塊時，此異常開始。

我webpack.config.js文件：

'use strict'; 

const webpack = require('webpack'); 
const path = require('path'); 
const webpackMerge = require('webpack-merge'); 
const CleanWebpackPlugin = require('clean-webpack-plugin'); 
const UglifyJsPlugin = require('webpack/lib/optimize/UglifyJsPlugin'); 
const CommonsChunkPlugin = require('webpack/lib/optimize/CommonsChunkPlugin'); 


// Webpack Config 
let webpackConfig = { 
    entry: { 
     'main': './src/main.ts', 
     'vendors': './src/vendors.ts' 
    }, 
    target: 'web', //https://webpack.js.org/configuration/target/ 
    output: { 
     publicPath: '', 
     path: path.resolve(__dirname, './dist') 
    }, 

    plugins: [ 
     new CleanWebpackPlugin(['./dist'], { 
      verbose: true, 
      dry: false 
     }), 


     new CommonsChunkPlugin({ 
      names: ['vendors'], 
      filename: '[name].js' 
     }), 


     new webpack.ContextReplacementPlugin(
      // The (\\|\/) piece accounts for path separators in *nix and Windows 
      /angular(\\|\/)core(\\|\/)src(\\|\/)linker/, 
      path.resolve(__dirname, './src'), 
      { 
       // your Angular Async Route paths relative to this root directory 
      } 
     ) 
    ], 

    module: { 
     rules: [ 
      { 
       enforce: 'pre', 
       test: /\.ts$/, 
       loader: 'tslint-loader', 
       exclude: /(node_modules)/ 
      }, 
      { 
       test: /\.ts$/, 
       use: [ 
        'awesome-typescript-loader', 
        'angular2-template-loader', 
        'angular2-router-loader' 
       ] 
      }, 
      { 
       test: /\.scss$/, 
       use: ['to-string-loader', 'style-loader', 'css-loader', 'postcss-loader', 'sass-loader'] 
      }, 
      { 
       test: /\.css$/, 
       use: ['to-string-loader', 'css-loader'] 
      }, 
      { 
       test: /\.html$/, 
       use: 'raw-loader' 
      } 
     ] 
    } 

}; 


// Our Webpack Defaults 
let defaultConfig = { 
    devtool: 'source-map', 

    output: { 
     filename: '[name].bundle.js', 
     sourceMapFilename: '[name].map', 
     chunkFilename: '[id].chunk.js' 
    }, 

    resolve: { 
     extensions: ['.ts', '.js'], 
     modules: [path.resolve(__dirname, 'node_modules')] 
    }, 

    devServer: { 
     historyApiFallback: true, 
     watchOptions: {aggregateTimeout: 300, poll: 1000}, 
     headers: { 
      "Access-Control-Allow-Origin": "*", 
      "Access-Control-Allow-Methods": "GET, POST, PUT, DELETE, PATCH, OPTIONS", 
      "Access-Control-Allow-Headers": "X-Requested-With, content-type, Authorization" 
     } 
    }, 

    node: { 
     global: true, 
     crypto: 'empty', 
     __dirname: true, 
     __filename: true, 
     process: true, 
     Buffer: false, 
     clearImmediate: false, 
     setImmediate: false 
    } 
}; 


module.exports = webpackMerge(defaultConfig, webpackConfig);

Answer 1

當webpackJsonp功能是不確定的運行時會出現此錯誤（顯然）呵呵，不過這是什麼意思？

因此，有三種類型的組塊中的WebPack：經由CommonsChunkPlugin其改善高速緩存能力創建

初始塊，然而它們是同步加載的，並且依賴於在所定義的webpackJsonp函數webpack運行時（aka條目塊）。

tl; dr您的腳本無序加載。如果您使用html-webpack-plugin，則可以在配置中使用它們的chunkSort選項來解決此問題。這也可能經常通過多個CommonsChunkPlugin的模糊組合來實現。

我最好的建議是刪除CommonsChunkPlugin並創建一個bundle，然後逐個將需要的代碼逐個拆分到不同的bundle中，以發現排序問題的發生位置。

Answer 2

包括vendor.js在index.html

這裏充滿的html代碼：

<!DOCTYPE html> 
<html lang="en" dir="ltr">

    <meta charset="UTF-8">

    <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no"> 
    <meta name="format-detection" content="telephone=no"> 
    <meta name="msapplication-tap-highlight" content="no"> 

    <link rel="icon" type="image/x-icon" href="assets/icon/favicon.ico"> 
    <link rel="manifest" href="manifest.json">

     .catch(err => console.log('Error', err)); 
    } 
    </script>--> 
    <!-- The vendor js is generated during the build process
