```
^[[999D  console.error node_modules/vuetify/dist/vuetify.js:25038                                                                                
    [Vuetify] Multiple instances of Vue detected                                                                                                 
    See https://github.com/vuetifyjs/vuetify/issues/4068                                                                                         
                                                                                                                                                 
    If you're seeing "$attrs is readonly", it's caused by this 
```

* The documentation clearly recommends to use `localVue.use(Vuetify)` so please do not suggest me to `Vue.use(Vuetify)` unless  if you are a superman with valid reasons able to convince me.

* I am using Jest   Nuxt   Vuetify. You can try my github repository provided in the above link.

I tried what that comments suggests:
```
Vue.use(Vuetify)
const localVue = createLocalVue()
localVue.use(Vuetify)
```
Still getting the exact same error. 
Thank you @username_1

I had same problem. 
it was due Capitalization of Vue
I changed "import Vue from 'Vue';" with "import Vue from 'vue';"
it works now

I had the same error, and for me, it was just as it says:

vuetify.js:53625 [Vuetify] **Multiple instances of Vue detected**
See https://github.com/vuetifyjs/vuetify/issues/4068

If you're seeing "$attrs is readonly", it's caused by this

I searched in my components code and realized I have vuetify called and vue inside components, and that was causing the error what I did is took those lines out and now I have only calling the vue from my vue.js file and the error was gone. 

Good Luck 👍
