Duplicate module on Windows if `build.rollupOptions.input` is relative path

sapphi-red commented 11 months ago

Describe the bug

If build.rollupOptions.input is relative path, like below,

import { defineConfig } from 'vite';

export default defineConfig({
  build: {
    rollupOptions: {
      input: {
        main: 'src/main.js',
        'lib/example': 'src/lib/example.js',
      },
    },
  },
});

the module is duplicated only on Windows. (In this example, src/lib/example.js is bundled twice. (This doesn't happen with rollup)

The workaround is to call path.resolve() (e.g. path.resolve('src/lib/example.js').

Can't find the difference between vite bundles and rollup bundles in the reproduction project, nor the duplicate module.

This only happens on Windows. Did you try it on Windows?
