Question

我有一个VUE 2应用程序，它不能与iisnode和iis一起运行。 iisnode的stderr日志说：ReferenceError：webpackJsonp未定义

节点版本：6.9.5 npm版本：4.3.0

这里经常提到这个主题，但解决方案并不适用于我。我的vendor.js在app.js之前加载，但是我收到了这个错误。

以下是我对webpack的配置文件：

bundle.js：

require('./check-versions')()

process.env.NODE_ENV = 'production'

var ora = require('ora')
var rm = require('rimraf')
var path = require('path')
var chalk = require('chalk')
var webpack = require('webpack')
var config = require('../config')
var webpackConfig = require('./webpack.prod.conf')

var spinner = ora('building for production...')
spinner.start()

rm(path.join(config.build.assetsRoot, config.build.assetsSubDirectory), err => {
  if (err) throw err
  webpack(webpackConfig, function (err, stats) {
    spinner.stop()
    if (err) throw err
    process.stdout.write(stats.toString({
      colors: true,
      modules: false,
      children: false,
      chunks: false,
      chunkModules: false
    }) + '\n\n')

    console.log(chalk.cyan('  Build complete.\n'))
    console.log(chalk.yellow(
      '  Tip: built files are meant to be served over an HTTP server.\n' +
      '  Opening index.html over file:// won\'t work.\n'
    ))
  })
})

webpack.base.conf.js：

我生成的index.html如下所示：

<!DOCTYPE html><html><head><meta charset=utf-8><title>CoreUI - Open Source Bootstrap Admin Template</title><link href=static/css/font-awesome.min.css rel=stylesheet><link href=static/css/simple-line-icons.css rel=stylesheet><link href=static/css/style.css rel=stylesheet><link href=static/css/app.06e44e579e587787413ab48c2c604c4d.css rel=stylesheet></head><body class="app header-fixed sidebar-fixed aside-menu-fixed aside-menu-hidden"><div id=app></div><script type=text/javascript src=static/js/vendor.2cb2e5935748c34893e8.js></script><script type=text/javascript src=static/js/app.9dc82c9f50710d9ababd.js></script></body></html>

我希望有人可以提供帮助。谢谢！

更新：取消联系你的代码：

// extract webpack runtime and module manifest to its own file in order to
// prevent vendor hash from being updated whenever app bundle is updated
new webpack.optimize.CommonsChunkPlugin({
 name: 'manifest',
 chunks: ['vendor']
}),

所以基本上注释掉你现在拥有的东西并取消注释这个:)。这将基本上将webpack拉入其自己的文件并在供应商文件之前插入它，并确保在窗口中注入缺少的函数。

这样做是因为webpack版本在开发过程中几乎永远不会改变，而其他插件/库/插件可能会发生变化，你可以将webpack与其他lib分开，这样每次添加时都不会被用户无用地下载新组件或更改某些版本并进行部署。
