我有一个大型骨干/ requirejs应用程序，我想迁移到webpack，最新的“ webpack”：“ ^ 4.27.1”，但遇到无法解决的错误。
我一直在阅读https://webpack.js.org/concepts/文档，并观看了Dodss的这段视频-https://www.youtube.com/watch?v=a96r7Tjf0Ps
我当前的webpack.config.js文件如下：
var path = require('path');
module.exports = {
mode: 'development',
context: path.resolve(__dirname),
entry: {
main: './public/assets/js/main',
base: './public/assets/js/base'
},
output: {
filename: '[name].js',
path: __dirname + '/dist'
},
resolve: {
alias: {
'/libs': './libs',
'events': path.resolve(__dirname, 'public/assets/js/events'),
'views': path.resolve(__dirname, 'public/assets/js/views'),
'models': path.resolve(__dirname, 'public/assets/js/models'),
'collections': path.resolve(__dirname, 'public/assets/js/collections'),
'templates': path.resolve(__dirname, 'public/assets/templates'),
'jquery': path.resolve(__dirname, 'public/assets/js/libs/jquery/jquery'),
'raven': path.resolve(__dirname, 'public/assets/js/libs/raven/raven'),
'backbone': path.resolve(__dirname, 'public/assets/js/libs/backbone/backbone'),
'daterangepicker': path.resolve(__dirname, 'public/assets/js/libs/daterangepicker/daterangepicker'),
'highchart': path.resolve(__dirname, 'public/assets/js/libs/highchart/highcharts'),
'intlTelInput': path.resolve(__dirname, 'public/assets/js/libs/intltelinput/intlTelInput'),
'mask': path.resolve(__dirname, 'public/assets/js/libs/inputmask/inputmask'),
'momentTimeZone': path.resolve(__dirname, 'public/assets/js/libs/moment-timezone/moment-timezone-with-data-2010-2020'),
'socket': path.resolve(__dirname, 'public/assets/js/libs/socket.io-client/socket'),
'kTranslate': path.resolve(__dirname, 'public/assets/js/utils/kTranslate'),
'detectizr': path.resolve(__dirname, 'public/assets/js/libs/detectizr/detectizr'),
'sjcl': path.resolve(__dirname, 'public/assets/js/libs/sjcl/sjcl'),
'authRouter': './authRouter',
'client': './client',
'router': './router',
'auth': './auth',
}
}
}
当我运行webpack --display-error-details时，项目中的许多文件似乎都捆绑在一起，但是我遇到关于node_modules的错误：
ERROR in ./node_modules/stream-browserify/node_modules/readable-stream/lib/internal/streams/stream-browser.js

我的项目架构如下：
app
-/public
/assets
/img
/js
/collections
/views
/events
/models
...
-/dist
-/node_modules
...
我尝试删除所有node_modules并重新安装，但这没用：
rm -rf node_modules
npm i
答案 0 :(得分：0)
万一这对任何人都有帮助，则问题与范围有关。如果您在我的webpack.config.js文件中看到，则包括以下行：
'events': path.resolve(__dirname, 'public/assets/js/events'),
这是用于主干的自定义事件文件。但是，在我的/node_modules中，我也有一个events模块，因此错误基本上是说stream-browser.js中存在问题，因为events无法使用我的配置设置，它指向我的自定义事件。
为了解决此问题，我将主干events文件夹重命名为backbone-events，然后编辑了受影响的那些文件。
