小白无能为力，求dalao指点。我也没用async.js啊

报错信息如下：

$ vue-cli-service build --mode production --dest dist --target app --dashboard

vue配置如下：

// vue.config.js
module.exports = {
    chainWebpack: config => {
        config.module
            .rule('md')
            .test(/\.md$/)
            .use('html-loader')
            .loader('html-loader')
            .end()
            .use('markdown-loader')
            .loader('markdown-loader')
            .end()
    }
}
