error while integrate custom theme with PrimeVue

[bingling-sama]

Describe the bug

When I import PrimeVue and configure it in the theme/index.ts file, I got a error:

4:34:33 PM [vitepress] Pre-transform error: Failed to resolve entry for package "primevue". The package may have incorrect main/module/exports specified in its package.json: Missing "." specifier in "primevue" package
4:34:33 PM [vitepress] Internal server error: Failed to resolve entry for package "primevue". The package may have incorrect main/module/exports specified in its package.json: Missing "." specifier in "primevue" package
  Plugin: vite:import-analysis

Reproduction

Create a vitepress project theme with custom theme:

pnpm add vitepress
pnpm vitepress init

choose all default but the Theme section:

◆  Theme:
│  ○ Default Theme (Out of the box, good-looking docs)
│  ○ Default Theme + Customization
│  ● Custom Theme

then add the PrimeVue lib:

pnpm add primevue @primevue/themes

use it in the theme/index.ts

// theme/index.ts
import Layout from './Layout.vue'
import type { Theme } from 'vitepress'
import './style.css'

import PrimeVue from "primevue"
import Aura from "@primevue/themes"

export default {
    Layout,
    enhanceApp({ app, router, siteData }) {
        // ...
        app.use(PrimeVue, {
            theme: {
                preset: Aura
            }
        })
    }
} satisfies Theme

then run pnpm docs:dev

Expected behavior

It should be running without any error, but i got a package error. It seems like there's some problem with vite:import-analysis

You should use import PrimeVue from 'primevue/config', check the docs https://github.com/primefaces/primevue/tree/master/packages/primevue#plugin
