[Vuejs]-Error: Module `@nuxtjs/vuetify` not found

In your project directory, run this command:

npm install –save-dev @nuxtjs/vuetify

I had the same issue and resolved it, the problem was the NODE_ENV when the NODE_ENV is set to production, it doesn’t install the dev dependencies. Check the NODE_ENV.

Please, remove your "@ nuxtjs / vuetify" from yours dependencies with the command:

 npm uninstall @ nuxtjs / vuetify

And then, install the dependencie in dev, with the next command:

 npm i @ nuxtjs / vuetify --save-dev

Good luck!
