run new SolidStart project in dev mode successfully. Old projects run fine.

same issue

[NielsHoogeveen]

I had the same issue as well. Using pnpm create solid@latest, pnpm install, pnpm dev. Didn't give the same issues.

[tcerqueira]

Same issue. I'm running npm version 10.9.0 and node version v22.11.0 on MacOS.

Edit: using pnpm solved the issue.

[threeaio]

Same Problem. :( ... checked some (not all!) package-versions and they all seem to be the same as in my working projects. Running on MacOS.
Using pnpm didn´t help :/
I copied the node_modules from a previous project and that worked.

[rpivo]

Also observed with npm on macos, but works with pnpm

[catlair]

❯ pnpm -v
9.11.0
❯ npm -v

❯ node -v

An error occurred in pnpm workspace

Works fine in pnpm (not workspace) or npm

[Just-a-Jason]

Same problem here. For a new project I copied node_modules folder from working project and it works fine, but I hope they will fix it soon.

[ryansolid]

I was able to reproduce this by updating to Vite 6 on the main project. So it is some sort of mismatch on versioning I think. I do use pnpm to be fair so I hadn't noticed it on any of the projects or examples until I made the vite 6 change. We also happen to be working on updating Vinxi and Vite versions so there should be a release soon that has all the matching versions again. I'm not sure how wrong versions are getting included. Something to do with package resolution and locking I guess but I'm gathering it has to do with sub dependencies depending on different versions of packages.

[Lunatic83]

Same issue on every pnpm create solid@latest example I've used.
I did investigate further using hackernews example using a 3 weeks old sandbox hackernews example in my local env
I've done the following steps:

pnpm create solid@latest
pnpm install
pnpn dev

At this stage I had the Client-only API on the server side error than I did

rm -Rf node_modules
# copy the pnpm-lock.yaml from the 3 weeks old sandbox
pnpm install
pnpm dev

Everything works with the old libs lock references I did perform a diff between the 2 pnpm-lock.yaml
I think some dependencies upgrade created a regression.

I found vite to have a dependency to a new version 6.0.2

I did force to override on the package.json with vite: 5.4.10
and it works.

This is my new package.json

{
 "name": "example-hackernews",
 "type": "module",
 "scripts": {
 "dev": "vinxi dev",
 "build": "vinxi build",
 "start": "vinxi start"
 },
 "dependencies": {
 "@solidjs/router": "^0.15.0",
 "@solidjs/start": "^1.0.10",
 "solid-js": "^1.9.2",
 "vinxi": "^0.4.3"
 },
 "pnpm": {
 "overrides": {
 "vite": "5.4.10"
 }
 },
 "engines": {
 "node": ">=18"
 }
}

[Lunatic83]

I think is something specifically with vite@6.0.2 I did override with version vite@6.0.1 and it works.

[martinliptak]

This package.json works for NPM (added "overrides"):

{
 "name": "example-basic",
 "type": "module",
 "scripts": {
 "dev": "vinxi dev",
 "build": "vinxi build",
 "start": "vinxi start",
 "version": "vinxi version"
 },
 "dependencies": {
 "@solidjs/meta": "^0.29.4",
 "@solidjs/router": "^0.15.0",
 "@solidjs/start": "^1.0.10",
 "solid-js": "^1.9.2",
 "vinxi": "^0.4.3"
 },
 "overrides": {
 "vite": "5.4.10"
 },
 "engines": {
 "node": ">=18"
 }
}

[birkskyum]

@Lunatic83 , is vite 6.0.3 any better? https://github.com/vitejs/vite/blob/v6.0.3/packages/vite/CHANGELOG.md

[caseybaggz]

I just tried 6.0.3 and it's still broken 😭
