Describe the bug

Hey,

I'm working on a monorepo (with turborepo) of a big project using Nuxt 2 as web interface.

I need to create a second web app which using Nuxt 3 but i can't start this app in the monorepo, i got this error when i try to install the project (pnpm i at root):

Scope: all 7 workspace projects
Lockfile is up to date, resolution step is skipped
Already up to date
apps/nuxt3-app postinstall$ nuxt prepare
│ Nuxi 3.0.0
│ ℹ Client built in 7475ms
│ ℹ Building server...
│  ERROR  [commonjs--resolver] Missing "./server-renderer" export in "vue" package
│  ERROR  Missing "./server-renderer" export in "vue" package

I think the problem is because the root node_modules is shared.

I just pushed a simple version of my project here which reproduce the problem:

Hey,

I dont think that this can be fixed as Nuxt 2 and Nuxt 3 have several different dependencies (including different versions of libraries). Because of that fixing this might be very difficult (not to mention that it is a rather not common use case 😉)

I would recommend to have apps in a separate repositories as this can cause even more issues later on.

This doesn't look like a Nuxt issue to me. I believe you will need to configure your dependency hoisting settings within pnpm: https://pnpm.io/npmrc#dependency-hoisting-settings.

[Suniron]

OK I will try to configure pnpm. Thanks for tips :-)

[Suniron]

Mmmh i don't understand how can i correctly set the hoisting..

[manzoliric]

@Suniron did you fixed? I'm with this same problem, i cannot use nuxt-2 and nuxt-3 in the same project using Pnpm 😢

[Suniron]

No, it's not fixes yet.

Currently, my nuxt 3 app is in Dev only I can't build it but I can build and Dev on Nuxt bridge projet (I migrate my nuxt 2 to nuxt bridge since I got this problem).
The Dev mode is OK with my Nuxt 3 app.

I dont need the production build before 2/3 next months, but I hope to find a solution soon 🤞

I have the same issue, haven't found a configuration that work yet. If anyone has a way to accomplish this; please do tell

[manzoliric]

I created this discussion in pnpm, maybe someone helps!
pnpm/pnpm#6104

[Suniron]

Thanks ! I'm always stucked with this problem..

@danielroe I'm also running into this issue with Yarn, so I think this might be a nuxt rather than pnpm issue. Even when the correct versions of nuxt and @nuxt/kit are in the local node_modules, nuxt tries to load them from the root. It looks to me like it might be related to unjs/mlly#158

[manzoliric]

@steffendybvik @Suniron, did you find a way to fix this problem?

[Suniron]

Not really, I had to put my Nuxt Bridge projet into a ''standalone'' folder (inside my monorepo to have all my apps in the same git project).

But I can't use packages :-(
