Postinstall script fails with PNPM workspaces due to npm ERR! Cannot read properties of null (reading 'matches')

Bug description

When running pnpm install in a monorepo, with this structure

packages
    server
         prisma
               schema.prisma
    shared-utils
         package.json
    web
         package.json
pnpm-workspace.yaml
package.json

I get this error:

#0 2.239
#0 2.239 > @hub/shared-utils@1.0.0 generate /app/packages/shared-utils
#0 2.239 > pnpm prisma generate

my package shared-utils installs prisma, web depends on shared-utils

shared-utils has a custom postinstall script, which generates Prisma client from custom location(from server package). This is package.json of shared-utils

{
  "name": "@example/shared-utils",
  "version": "1.0.0",
  "main": "dist/src/index.js",
  "types": "dist/src/index.d.ts",

  },
  "prettier": "@example/prettier-config",
  "jest": {
    "preset": "ts-jest",
    "roots": [
      "src"
    ],
    "modulePaths": [
      "src"
    ],
    "moduleDirectories": [
      "node_modules"
    ]
  }
}

How to reproduce

1. Go to project root.
2. Run pnpm install
3. See error

Expected behavior

pnpm install installs packages, and Prisma schema is generated automatically

adding public-hoist-pattern[]=*prisma* to .npmrc file fixed this issue, took the solution from here

@janpio when will Prisma support PNPM? 👀

seems like this is related to these issues, but I still haven’t managed to make it work https://github.com/prisma/prisma/issues/9848 https://github.com/prisma/prisma/discussions/12501
