Describe the Bug

I can't build the project with outDir astro option. I get this error

18:26:11 [ERROR] [vite] x Build failed in 736ms
[vite]: Rollup failed to resolve import "virtual:astro-icon" from "/home/node/reikiolistique/node_modules/astro-icon/components/Icon.astro".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
`build.rollupOptions.external`

What's the expected result?

No error, regular build. The project builds without the outDir option.

Build any project with the option outDir

I had the same error and i solved it by adding the astro-icon integration in astro.config.mjs like described here: https://github.com/natemoo-re/astro-icon?tab=readme-ov-file#manual-install
