sourcemap in Vite dev mode with pnpm is incorrect

[agileago]

What happens and why it is wrong

Environment

as a vite plugin to develop

Versions

latest

repo: clone https://github.com/agileago/vue3-oop

pnpm install
pnpm run dev

you will see count.service.ts sourcemap is not right and can't breakpoint . but when you change vite.config.ts to use @rollup/plugin-typescript . it is ok. because @rollup/plugin-typescript is too slow. by the way. because i use decorator so i need typescript compile not esbuild

Since OP did not link a permalink, I had to find an old git tag myself in their repo to find the code. I also can't read the language it's written in (Chinese I assume? based on the alphabet and Vue's popularity there)

There's a confounding issue here with pnpm that may be the cause but it's hard to tell with a complicated repo like that. A minimal reproduction would be very helpful, see the repro environment here.
If you were using any symlinks with pnpm, you may have hit #234. That was recently fixed in #332 and released in 0.32.0
