npm run dev fails to compile fresh new nuxt.js project.

Nuxt.js v1.4.0

How to reproduce:

vue init vuetifyjs/nuxt my-project
cd my-project
npm i
npm run dev

You will see this error in the console:

⋊> ~/c/my-project npm run dev

> my-project@1.0.0 dev /Users/vasyl/code/my-project
> nuxt

Module build failed: ValidationError: PostCSS Loader Invalid Options

options['useConfigFile'] is an invalid additional property

Temporary not really stable workaround.

• Open the file ./node_modules/nuxt/lib/builder/webpack/postcss.js
• Comment out the line with useConfigFile: false
• Run npm run dev - all OK this time.
