Upgrade chokidar to fix Nuxt 4 Nitro build
I recently upgraded @nuxt/ui to version 4, which uses your package unplugin-vue-components version 29.1.0.
This pulls a dependency for chokidar version 3.6.0, which itself pulls a dependency for anymatch 3.1.3, which itself pulls a dependency for a very outdated version of picomatch, version 2.3.1, before they removed the dependency on the "path" nodejs library.
This causes the following error when building a Nuxt 4 project:

anymatch has not been updated in 3 years, so this is to be expected. However, chokidar version 4 dropped all dependencies except one, including the drop of anymatch.
I don't know how no one else got this error, but I think it would be beneficial for everyone if your project upgraded to chokidar version 4.
As I mentionned on https://github.com/nuxt/ui/issues/5241, Turns out the issue was already there in Nuxt UI 3 but only occurs with Nuxt 4's stricter requirements for ES module (ESM) compatibility. And since the migration guide (https://ui.nuxt.com/docs/getting-started/migration/v4) says
Nuxt UI v4 requires Nuxt 4 due to some dependencies. Make sure to upgrade to Nuxt 4 before migrating to Nuxt UI v4.
it's going to become an issue when upgrading to version 4
