Svelte 5 not working in monorepo

peterreeves commented 3 months ago

Describe the bug

Svelte 5 appears not to work in monorepo setups. I've tried both a setup with turborepo, and a smaller setup just using NPM workspaces. I've included the turborepo setup below as it's simpler to setup.

Reproduction

( Following the turborepo example https://github.com/vercel/turbo/tree/main/examples/with-svelte )

npx create-turbo@latest -e with-svelte

After setup, observe that npm run dev works correctly when visiting the page..

Update either of the "web" or "docs" project with "svelte": "^5.0.0-next.1" and run npm i. Run npm run dev again, and see that the page no longer loads, with this error displayed (filepaths edited):

TypeError: __vite_ssr_import_0__.create_ssr_component is not a function

Small update, I just tried this again with pnpm and it works correctly. I guess this might be the kick I need to start switching my projects from npm to pnpm...

I bumped into this too... using npm workspace with both svelte4 and 5 packages in it.
