未捕獲的類型錯誤：升級到 webpack 3 時無法讀取未定義的屬性（讀取“調用”）

Question

我正在開發一個谷歌瀏覽器擴展，今天我嘗試將 webpack 升級到版本 3（舊版是 webpack 1.x）。 現在我幾乎完成並且編譯工作正常，但是當我打開谷歌瀏覽器擴展彈出頁面時，它無法顯示 UI 元素。 然后我打開彈出 debbbugger 控制台並顯示錯誤日志：

Uncaught TypeError: Cannot read properties of undefined (reading 'call')
    at __webpack_require__ (bootstrap 9e5832947e0eb0ffd7bf:54:1)
    at Object.500 (popup.js:115:1)

我檢查了引導程序"bootstrap-sass": "^3.4.1",版本，它是最近一次更新是 3 年前的最新版本。 為什么會這樣？ 我應該怎么做才能解決這個問題？ 這是我的項目package.json ：

    "webpack": "^3.12.0",
    "webpack-cli": "^4.9.1"
  },
  "license": "GPLv3",
}

這是我的 webpack 配置：

const path = require('path');
const webpack = require( 'webpack' ) ,
  CommonsChunkPlugin = webpack.optimize.CommonsChunkPlugin ,
  ExtractTextPlugin = require( 'extract-text-webpack-plugin' );

module.exports = {
  entry : {
    bg : './src/background-scripts/' ,
    content : ['./src/content-scripts/firefox-fix.js', './src/content-scripts/'] ,
    options : './src/options/' ,
    popup : './src/popup/' ,
    'bs-lite' : './src/public/bootstrap-lite.scss'
  } ,
  output : {
    path : path.resolve(__dirname, '../src/bundle') ,
    filename : '[name].js'
  } ,
  module : {
    rules : [
      {
        test : /\.js$/ ,
        exclude : [ /node_modules(?!(\/|\\?\\)(translation\.js|selection-widget|connect\.io|chrome-env)\1)/ ] ,
        loader : 'babel-loader'
      } ,
      {
        test : /\.woff$/ ,
        loader : 'file-loader' ,
        query : {
          name : '[name].[ext]'
        }
      } ,
      {
        test : /\.html$/ ,
        loader : 'vue-html-loader'
      } , 
      {
        test : /\.(css|scss)$/ ,
        use: ExtractTextPlugin.extract({
          fallback :'style-loader',
          use: [
            'css-loader',
            {
              loader: 'sass-loader',
              options: {
                implementation: require('sass')
              }
            }]
        })
      }
    ]
  } ,
  plugins : [
    new CommonsChunkPlugin( {
      name : 'commons1',
      filename : 'commons1.js' , 
      allChunks: true,
      chunks : [ 'content' , 'popup' ] 
    }) ,
    new CommonsChunkPlugin({ 
      name: 'commons2',
      filename :'commons2.js' , 
      allChunks: true,
      chunks : [ 'commons1.js' , 'options' ] 
    }) ,
    new CommonsChunkPlugin({ 
      name: 'commons3',
      filename :'commons3.js' , 
      allChunks: true,
      chunks : [ 'bg' , 'commons2.js' ] 
    }) ,
    new ExtractTextPlugin( '[name].css' )
  ]
};

我不知道如何解決這個問題，有人遇到同樣的問題嗎？ 我試圖在 CommonsChunkPlugin 中添加allChunks: true但沒有用。 我還嘗試將彈出塊移動到其他人的前面來控制這樣的順序：

new CommonsChunkPlugin( {
      name : 'commons1',
      filename : 'commons1.js' , 
      allChunks: true,
      chunks : [ 'popup','content' ],
      chunksSortMode: 'manual',
    }) ,

仍然沒有工作。 有人面臨同樣的問題嗎？

問題很簡單。 可能您在同一頁面上使用通過 weback 構建的多個應用程序。 解決方法： 更改output.jsonpFunction
