@JounQin sorry you ran into a spot of trouble.
Could you produce a minimal reproducible example?

It works in my testing https://stackblitz.com/edit/vitejs-vite-4txvc5?file=package.json

[JounQin]

@ChristianMurphy Did you try my linked https://github.com/un-ts/mono-lib-boilerplate?

[ChristianMurphy]

@JounQin have you tried reducing the issue? Or using an official release of vite instead of a patched version?
I'm at a conference right now, but if you're stuck I may be able to help you debug your personal project later.

[JounQin]

@ChristianMurphy The reproduction is tiny.

The patch is also tiny for vitejs/vite#15281

---

I do cannot reproduce on stackblitz: https://stackblitz.com/edit/vitejs-vite-mt6zzg?file=vite.config.ts,src%2Fmain.tsx

I'm still trying to add react-router-dom.

Which repo do you mean? I see a link to https://github.com/un-ts/mono-lib-boilerplate which is giant?

[wooorm]

From the Vite issue and your patch, it seems a Vite bug?

The vite part is only docs folder. Maybe really a Vite bug which does not support nested folder anymore, I'll find out later.

[JounQin]

I really can't find out what is going on... I changed almost everything on stackblitz just like my mono-lib-boilerplate, but it just works differently...

@ChristianMurphy If you can help to debug when you're free that would be very appreciated.

[ChristianMurphy]

@JounQin have you tried installing via npm instead of yarn?
My next thought is that resolutions and how the folders are laid out are different between the two.

Just tried, it didn't help.

[ChristianMurphy]

@JounQin I see some more changes landed in un-ts/mono-lib-boilerplate are you still having a vite issue? or has it been resolved?

[JounQin]

Thanks for still remembering this issue, it is indeed an issue from Vite itself.
