升级到16后，为什么我的反应应用程序在生产版本上失败？

升级后对版本16的反应我的应用程序停止工作生产构建，当运行开发工作正常。如果我降级到React 15.6，它仍然适用于prod和dev环境。

我正在使用："webpack": "^3.5.6",和"react": "^16.0.0",

我收到以下错误：

未捕获的ReferenceError：未定义require

我的webpack prod配置：

const path = require('path');
const merge = require("webpack-merge");
const webpack = require("webpack");
const config = require("./webpack.base.babel");

const OfflinePlugin = require('offline-plugin');
const HtmlWebpackPlugin = require("html-webpack-plugin");

module.exports = merge(config, {
  // devtool: "nosources-source-map",
  devtool: "source-map",
  // In production, we skip all hot-reloading stuff
  entry: [
    'babel-polyfill', // Needed for redux-saga es6 generator support
    path.join(process.cwd(), 'src/client/app.js'), // Start with app.js
  ],
  performance: {
    assetFilter: (assetFilename) => !(/(\.map$)|(^(main\.|favicon\.))/.test(assetFilename)),
  },
  plugins: [
    new webpack.LoaderOptionsPlugin({
      minimize: true
    }),
    new HtmlWebpackPlugin({
      template: "src/client/index.html",
      minify: {
        removeComments: true,
        collapseWhitespace: true,
        removeRedundantAttributes: true,
        useShortDoctype: true,

        minifyCSS: true,
        minifyURLs: true,
      },
      inject: true,
    }),
    // Shared code
    new webpack.optimize.CommonsChunkPlugin({
      name: "vendor",
      children: true,
      minChunks: 2,
      async: true,
    }),
    // Avoid publishing files when compilation fails
    new webpack.NoEmitOnErrorsPlugin(),
    // Put it in the end to capture all the HtmlWebpackPlugin's
    // assets manipulations and do leak its manipulations to HtmlWebpackPlugin
    new OfflinePlugin({
      relativePaths: false,
      publicPath: '/',

      // No need to cache .htaccess. See http://mxs.is/googmp,
      // this is applied before any match in `caches` section
      excludes: ['.htaccess'],

      caches: {
        main: [':rest:'],

        // All chunks marked as `additional`, loaded after main section
        // and do not prevent SW to install. Change to `optional` if
        // do not want them to be preloaded at all (cached only when first loaded)
        additional: ['*.chunk.js'],
      },

      // Removes warning for about `additional` section usage
      safeToUseOptionalCaches: true,

      AppCache: false,
    }),
  ]
});

我该如何解决？

修复很简单。

我只需删除此行noParse: /\.min\.js/

其中：

防止webpack解析与给定常规文件匹配的任何文件表达式（多个）。忽略的文件不应该有导入，require，定义或任何其他导入机制。
