error during build: EACCES: permission denied, copyFile

[yunics-highfield]

When I used vite-plugin-static-copy for building, I got an error below. Why does this happen? And how do I solve it?

error during build:
EACCES: permission denied, copyFile '/home/projects/vitejs-vite-mmjbfj/src/version.json' -> '/version.json'

Reproducer
https://stackblitz.com/edit/vitejs-vite-mmjbfj?file=vite.config.js,src%2Fversion.json&terminal=dev

Reproduction steps

1. Stop vite.
2. Run vite run build.

It didn't reproduce on my Windows machine or stackblitz.

Sorry about that. I modified the stackblitz by accident (I modified it back.). And I solved it myself. If you set root path to dest, it must be "", not "/". If you set "/" it might fail to build in some files.
