Plugin vue-cli-plugin-vuetify does not have a generator to invoke

This happens using any of the following project init scripts:

• npm init @vitejs/app my-beta-app -- --template vue
• yarn create @vitejs/app my-beta-app --template vue
• npm init vue@latest
• npm create vite@latest my-vue-app -- --template vue
• yarn create vite my-vue-app --template vue

All except .jsx support.

I've used the script yesterday and it worked without issues. Is there something I could have done that would cause this?

[MajesticPotatoe]

which prompt are you selecting during vue add vuetify? i did yarn create @vitejs/app my-beta-app --template vue which doesn't provide any prompts, and then during vue add vuetify i selected Vite Preview (Vuetify 3 + Vite).

its possible with the other templates, depending on what options are selected with the initial vue package creation that there are some conflict of dependencies or something isn't getting set up correctly

The problem is that vue add vuetify don't prompt me 😅. Instead it returns this Plugin vue-cli-plugin-vuetify does not have a generator to invoke message.

I assume the "generator" is the cli prompt that would ask me between Vuetify2, Vuetify3, etc.

[rafaellehmkuhl]

One thing I've just remember, and I would like to add: I'm using yarn 3.2.1, and I'm pretty sure by the time the prompt worked, I was using yarn classic.

Edit: there's clearly something to do with Yarn, and probably with it's latest version.

Following worked (vuetify-cli prompt called):

npm init vue@3
cd project_name
npm install
vue add vuetify

Following don't work (vuetify-cli prompt not called and message Plugin vue-cli-plugin-vuetify does not have a generator to invoke returned):

yarn create vue@3
cd project_name
yarn install
vue add vuetify

To make it clear,yarn --version gives me 3.2.1.

Confirmed it works properly with yarn 1.23.0.

@MajesticPotatoe using yarn 1.23.0 I moved forward and begin to test other parts. One thing that also appears not to be working is the integration of Vuetify3 with Vitest. I used the Vite Preview (Vuetify3 + Vite) option, and when running the unit test with yarn test:unit I received the following:

➜  cockpit git:(initial-project-structure) ✗ yarn test:unit
yarn run v1.23.0-20220130.1630

In this case, the CounterCard component is a bare component with a <v-btn>, but the problem ("unknown file extension '.css'") happens when using any Vuetify component.
