在对我的 karma.conf.js 进行更改以允许 Karma Coverage 之后，运行 karma 现在会失败。我不确定发生了什么。有什么想法吗？

process.env.NODE_ENV = 'test';

module.exports = function(config) {
    config.set({
    autoWatch: true,
    browsers: ['Chrome'], //, 'Firefox', 'Safari'],
    frameworks: ['jasmine'],
    logLevel: config.LOG_INFO,
    singleRun: false,
    port: 9876,
    colors: true,
    concurrency: Infinity, // how many browser should be started simultaneous
    files: [
        'test/**/*Spec.js',
        'src/**/*.js' //ADDED FOR COVERAGE
    ],
    preprocessors: {
        'test/**/*Spec.js' : ['babel', 'webpack', 'sourcemap'],
        'src/**/*.js' : ['babel', 'webpack', 'sourcemap', 'coverage'] //ADDED FOR COVERAGE

    },
    reporters: ['progress', 'coverage'], //ADDED FOR COVERAGE
    coverageReporter: { //ADDED FOR COVERAGE
        type : 'html',
        dir : 'coverage/'
    },
    webpack: {
        devtool: 'inline-source-map',
        resolve: {
            extensions: ['', '.js', '.jsx'],
            modulesDirectories: [
                'node_modules'
            ]
        },
        module: {
            loaders: [
                {
                    test: /\.(js|jsx)$/,
                    exclude: /(node_modules)/,
                    loader: 'babel-loader'
                },
                {
                    test: /\.css$/,
                    loader: "style-loader!css-loader"
                }
            ]
        },
        externals: {
            'cheerio': 'window',
            'react/addons': true,
            'react/lib/ExecutionEnvironment': true,
            'react/lib/ReactContext': true
        }
    },
    webpackServer: {
        noInfo: true //don't spam the console when running in karma!
    },

    plugins: [
        "karma-babel-preprocessor",
        "karma-chrome-launcher",
        "karma-webpack",
        "karma-sourcemap-loader",
        "karma-jasmine",
        'karma-coverage'  //ADDED FOR COVERAGE
    ],

    babelPreprocessor: {
        options: {
            presets: [
                "latest",
                "react-app"
            ],
            sourceMap: 'inline',
            plugins: [
                "transform-object-rest-spread"
            ]
        }
    }
})
}

我收到以下错误（下面还有更多类似的错误）
