看起来与Babel unexpected token import when running mocha tests有关并且可能是重复但是，在尝试了这些解决方案之后，我仍然面临着问题 .

尝试使用Mocha运行一些测试：

./node_modules/.bin/mocha --compilers js：babel-core / register

Issue

$ ./node_modules/.bin/mocha --compilers js：babel-core / register C：\ devel \ jtreports \ node_modules \ react-widgets \ lib \ less \ react-widgets.less：1（function（exports，require） ，module，__ filename，__ dirname）{@ import“./variables.less”; ^语法错误：exports.runInThisContext中的意外标记ILLEGAL（vm.js：53：16）

首先不确定为什么导入（必须有错误配置的东西）是一个问题，其次，node_modules正在处理？期望根据下面的webpack配置排除node_modules目录 .

webpack.config.js:

const webpack = require('webpack');

module.exports = {
    entry: [
        'webpack-dev-server/client?http://localhost:80',
        './app/main.js'
    ],
    output: {
        path: './app',
        filename: 'app.bundle.js'
    },
    module: {
        loaders: [
            {
                test: /\.js?$/,
                exclude: /node_modules/,
                loaders: ["babel-loader"]
            },
            {
                test: /\.css$/,
                loader: "style-loader!css-loader"
            },
            {
                test: /\.less$/,
                loader: "style-loader!css-loader!less-loader"
            },
            {
                test: /\.woff(2)?(\?v=[0-9].[0-9].[0-9])?$/,
                loader: "url-loader?mimetype=application/font-woff"
            },
            {
                test: /\.(ttf|eot|svg)(\?v=[0-9].[0-9].[0-9])?$/,
                loader: "file-loader?name=[name].[ext]"
            },
            {
                test: /\.(jpe?g|png|gif|svg)$/i,
                loaders: [
                    'file?hash=sha512&digest=hex&name=[hash].[ext]',
                    'image-webpack?bypassOnDebug&optimizationLevel=7&interlaced=false'
                ]
            }
        ]
    },
    resolve: {
        extensions: ['', '.js', '.jsx']
    },
    devServer: {
        hot: true,
        inline: true,
        host: 'localhost',
        port: 80,
        contentBase: "./app",
        secure: false,
        colors: true,
        noInfo: false,
        proxy: {
            '/rest': {
                target: 'http://localhost:8080',
            }
        },
        historyApiFallback: true
    },
    plugins: [
        new webpack.HotModuleReplacementPlugin()
    ]
}
