Environment

Linux x64, NodeJS v22.15.0

Reproduction

I've created a minimal reproduction repo using pnpm monorepo + Nitro + Prisma, which reliably reproduces the bug on my machine (Linux x64, NodeJS v22.15.0):

Describe the bug

In a pnpm monorepo environment, Nitro appears to have issues resolving module paths when importing local workspace packages.

The specific symptom is that in .nitro/dev/index.mjs (or .nuxt/dev/index.mjs), incorrect relative paths are being generated for the imported Prisma client:

import { PrismaClient } from '../../../../../../../../../packages/database/generated/client';

This path contains an excessive number of ../, clearly going beyond the valid directory structure. In VSCode, this path also cannot be clicked through or resolved.

Meanwhile, all other imports are using absolute paths like this:

import consola from 'file:///home/magma/projects/nitro-prisma-monorepo-debug/node_modules/.pnpm/[email protected]/node_modules/consola/dist/index.mjs';
import { ErrorParser } from 'file:///home/magma/projects/nitro-prisma-monorepo-debug/node_modules/.pnpm/[email protected]/node_modules/youch-core/build/index.js';
import { Youch } from 'file:///home/magma/projects/nitro-prisma-monorepo-debug/node_modules/.pnpm/[email protected]/node_modules/youch/build/index.js';
import { SourceMapConsumer } from 'file:///home/magma/projects/nitro-prisma-monorepo-debug/node_modules/.pnpm/[email protected]/node_modules/source-map/source-map.js';
import { Server } from 'node:http';

Only the Prisma import uses a relative path — all others use absolute file URLs. This leads to runtime errors when trying to use the Prisma client inside Nitro:

Cannot find module '/packages/database/generated/client' imported from /home/magma/projects/nitro-prisma-monorepo-debug/apps/nitro/.nitro/dev/index.mjs

And the build also fails as a result.
