[Vuetify] Multiple instances of Vue detected

[begueradj]

Version

1.0.0-beta.29

Reproduction link

https://github.com/begueradj/bugs/tree/master/nuxtVuetifyJest

Steps to reproduce

const localVue = createLocalVue()
localVue.use(Vuetify)

What is expected?

I expect my test to pass without any error or warning messages.

What is actually happening?

The test passes but I receive this nasty red message:

^[[999D  console.error node_modules/vuetify/dist/vuetify.js:25038

    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.

Please see this comment in Vuetify—vuetifyjs/vuetify#4068 (comment)

I tried what that comments suggests:

Vue.use(Vuetify)
const localVue = createLocalVue()
localVue.use(Vuetify)

Still getting the exact same error.
Thank you @eddyerburgh

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