webpack 4 react build会导致令牌错误，但运行开始有效

在使用webpack构建之后，我收到了Uncaught SyntaxError：意外的令牌错误。我能够运行start，它将以这种方式加载。所以我知道这一定是输出问题，或者我想象。

index.html正在生成，bundle.js也是如此。我把它作为index.html文件的路径。我正在使用webpack 4并拥有以下webpack.config.js

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin')

module.exports ={
    entry: './src/index.js',
    output: {
        path: path.join(__dirname, 'build'),
        filename: 'bundle.js'
    },
    module: {
        rules: [
            {
                loader: 'babel-loader',
                test: /\.js$/,
                exclude: /node_modules/
            }
        ]
    },
    devServer: {
        host: 'localhost',
        port: '8080'
      },
    plugins: [
        new HtmlWebpackPlugin({
            template: './src/index.html'
        }),

    ]
}
