05-shopping_cart app has module was not found error

[DevAVIJIT7]

Thanks for this opensource repository. It's helps a lot to learn vue js while reading the book.
There is one issue in your shopping cart app. When I run npm run client, It's giving

This relative module was not found:

* ./productListItem in ./node_modules/babel-loader/lib!./node_modules/vue-loader/lib/selector.js?type=script&index=0!./src/app/components/product/ProductList.vue .

That need to change to
import ProductListItem from './ProductListItem';

Thanks
