npm run build take forever to complete

Question

I am trying to "npm run build" to produce a dist folder for vue deployment. The command seems to run for a while and stuck there forever. The process stuck at the following part:

        + 1 hidden module
Child mini-css-extract-plugin node_modules/css-loader/index.js??ref--4-1!node_modules/vue-loader/lib/loaders/stylePostLoader.js!node_modules/postcss-loader/src/index.js??postcss!node_modules/sass-loader/dist/cjs.js??ref--4-3!node_modules/vue-loader/lib/index.js??vue-loader-options!src/views/Landing/Policy.vue?vue&type=style&index=0&id=796e3c9a&lang=scss&scoped=true&:

        + 1 hidden module

Any idea what is happening and how to overcome it?

Thanks in advance.
