Hi guys, I follow the Vue-CLI 3 guide and when I try to compile the source code the terminal show me a Typescript error.

$ vue create my-app
$ cd my-app
$ vue add vuetify

Expected Behavior

The Typescript code should compile.

Actual Behavior

2:21 Could not find a declaration file for module 'vuetify/lib'. 'C:/project/path/node_modules/vuetify/lib/index.js' implicitly has an 'any' type.
  Try `npm install @types/vuetify` if it exists or add a new declaration (.d.ts) file containing `declare module 'vuetify/lib';`
    1 | import Vue from 'vue'
  > 2 | import Vuetify from 'vuetify/lib'
      |                     ^
    3 | import 'vuetify/src/stylus/app.styl'
    4 |
    5 | Vue.use(Vuetify, {

@KaelWD Thank you for the link. More specifically, this comment helped me out to properly update my tsconfig.json:

"compilerOptions": {
  "types": ["...", "vuetify"],

In our projects, we use vue add vuetify approach to add Vuetify into our project.

The generated file plugins/vuetify.ts has this line:

import Vuetify from 'vuetify/lib';

remove the /lib from to import Vuetify from 'vuetify';

it will solve the issue. 🥂
