I digged down this and found that this was happening because tryNodeResolve was stripping ?used. (element-plus has exports field)

This is the same reason for #6725 and it will be fixed with #7098.
It worked when I tried with #7098 actually.

Hey, I tested it locally with your code https://github.com/sapphi-red/vite/tree/fix/import-with-query-exports-field and it didn't fix the problem I mentioned

[sapphi-red]

I tried again and it did work for me.

How did you test it? Did you follow this? Maybe you forgot to run pnpm build in vite repository?

[xiaoxian521]

Just started looking at vite and I'm not sure my steps are correct
pnpm install
pnpm build-vite
cd packages/vite
pnpm link vite --global

[sapphi-red]

I am not familiar with pnpm link but I think you are using it incorrectly.

I suppose running pnpm link /path/to/vite in your project will work.

you can try: https://vitejs.dev/guide/#using-unreleased-commits

I tried that now and it did work for me also.

Did you run pnpm link --global vite in your project? (I first forgot to run it.)
