Reactjs SourceNode.fromSourceWithMap不是mocha env loader中的函数

我正试图将业力整合到通用路由的反应中。我删除了公共区块插件，因为在karma webpack中使用公共区块时出错

我现在的错误是：

Uncaught Error: Module build failed: TypeError: SourceNode.fromSourceWithMap is not a function
      at Object.module.exports (/Users/jgs/Projects/react/MyApp/node_modules/karma-webpack/lib/mocha-env-loader.js:16:29)

可以将karma webpack与react和文件分块一起使用吗？

如果您使用karma-webpack_2 npm模块，在karma webpack中使用分块的问题似乎可以得到解决

还有其他工作要配置我的karma配置，并从网页包配置中重用module.rules数组

const webpackConfig = require('./tools/webpack.config').default[0];

// let commonsChunkPluginIndex = webpackConfig[0].plugins.findIndex(plugin => plugin.chunkNames);
// webpackConfig[0].plugins.splice(commonsChunkPluginIndex, 1);
// commonsChunkPluginIndex = webpackConfig[0].plugins.findIndex(plugin => plugin.chunkNames);
// webpackConfig[0].plugins.splice(commonsChunkPluginIndex, 1);

// let module = webpackConfig;
// console.log(webpackConfig);
webpackConfig.module.rules.push({ test: /\.js$/, loader: 'babel-loader' })
module.exports = function(config) {
    config.set({

        browsers: [ 'Chrome' ], //run in Chrome
        singleRun: true, //just run once by default
        // ... normal karma configuration
        frameworks    : ['mocha'],
        // reporters     : ['mocha'],
        files: [
            // all files ending in "_test"
            'src/*test.js',
            'src/**/*test.js'
            // each file acts as entry point for the webpack configuration
        ],

        preprocessors: {
            // add webpack as preprocessor
            'src/*test.js': ['webpack'],
            'src/**/*test.js': ['webpack']
        },

        // webpack: {
        //     // you don't need to specify the entry option because
        //     // karma watches the test entry points
        //     // webpack watches dependencies

        //     // ... remainder of webpack configuration (or import)
        // },

        // webpack: webpackConfig,
        webpack: {
          devtool: 'inline-source-map',
          // module: {

          //   ]
          // }
         module: webpackConfig.module 
        },        

        webpackMiddleware: {
            // webpack-dev-middleware configuration
            // i.e.
            noInfo: true,
            // and use stats to turn off verbose output

                chunks: false
            }
        },

        plugins: [
            require("karma-webpack"),
            require('karma-mocha'),
            require('karma-chrome-launcher')

    });
};
