Unknown custom element with Storybook and Vuetify

I try to use Vuetify with Storybook.

First, i create the project

vue create identity-card

Add Storybook

npx -p @storybook/cli sb init

Install Vuetify

vue add vuetify

Add vue-cli-plugin-vuetify-storybook

vue add vuetify-storybook

Install js-beautify

npm install js-beautify

And run

npm run storybook

I create a folder "Login" in components

Create the "LoginForm.vue", from https://vuetifyjs.com/en/examples/layouts/centered/

And add "LoginForm.stories.js"

import MyLoginForm from './LoginForm.vue';

export default {
    title: 'LoginForm',
    component: MyLoginForm,
}

export const Template = (args, { argTypes }) => ({
    props: Object.keys(argTypes),
    components: { MyLoginForm },
    template: `<my-login-form />`
});

But i have a lots of error like "Unknown custom element: ". What did I do wrong ?
