app.component is not a function

I apologize for the confusion. In UniApp, the `app.component` method is not available for registering global components in Vue 3. Instead, you can use the `createApp` function provided by Vue 3 to create your app instance and register global components.
Here's an example of how you can register a global component in UniApp using Vue 3:
1. Create your component file, e.g., `MyComponent.vue`, in the `components` directory.
2. In your `App.vue` file, import the `createApp` function and your component, and register the component using the `component` method:
```vue
<template>
<view>
<my-component></my-component>
</view>
</template>
<script>
import { createApp } from 'vue'
import MyComponent from '@/components/MyComponent.vue'
export default {
created() {
const app = createApp({})
app.component('my-component', MyComponent)
app.mount('#app')
}
}
</script>
```
Make sure you have the necessary setup to mount your app using `app.mount` with the appropriate element ID (`#app` in this example).
This way, your component will be registered globally, and you can use it in any page of your UniApp project.
I apologize for any confusion caused by my previous response. I hope this clears up the confusion. If you have any further questions, please let me know!
