Javascript postcss正在处理/css/app.css，并在导入vue2日期范围选择器后抛出CssSyntaxError

我正在一个laravel项目中与vue一起编写SPA，并使用laravel mix（

npm run watch

等）构建资产 在vue组件中导入

vue2日期范围选择器之前，一切正常

npm运行监视

及

npm运行开发

它们很好

但是当我跑的时候

npm运行生产

它抛出这样一个错误

> @ production /my-project
> cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

还有我的

mix.version（）；
混音({
插件：['@babel/plugin语法动态导入']，
});
mix.webpackConfig({
输出：{
chunkFilename:'js/[name].[chunkhash].js'，
},
});
混合料({
启用：对，
目标：[
“覆盖率99.5%，
],
});
js（'resources/assets/js/app.js'，'public/js'）；
mix.sass（'resources/assets/sass/app.scss'，'public/css'）；

但我仍然可以跑步

npm运行生产

但是分别构建CSS和JavaScript

//mix.js（'resources/assets/js/app.js'，'public/js'）；
mix.sass（'resources/assets/sass/app.scss'，'public/css'）；

mix.js（'resources/assets/js/app.js'，'public/js'）；
//mix.sass（'resources/assets/sass/app.scss'，'public/css'）；

我怎么跑

npm运行生产

只有一次？
我用我自己的版本创建了这个库，
npm-run-production
开始工作了

但在Chrome中，控制台开始抛出一些错误，如，并由解决。
