Did you find the real reason why contant's weren't defined in Vue?

[sheremet-va]

Also shouldn't they be statically replaced? And not just declared on a global?

the file will generate vite ssr code, and exec in the vm. and the vm don't had load vite env. vite env inject the global vari when run in the serve or ssr mode.

Oh, interesting finding. But I guess importing /@vite/env once should be enough.
You can try to have await runner.executeId('/@vite/env') before:

vitest/packages/vite-node/src/cli.ts

Lines 87 to 88 in d55736d

	for (const file of files)
	await runner.executeFile(file)

oh, they only run in the difference worker, vm had the same context with worker 😂
