When not installing globally: `Cannot find module 'ajv/dist/compile/codegen'`

[thany]

This error doesn't happen when installing orval globally and calling it straight away. This error only happens when installing orval like this:

npm i -D orval

And then executing it through an npm script in the package.json:

{
  "scripts": {
    "openapi": "orval --config orval.config.ts"
  },
  // ...
}

Full error:

>npm run openapi

> @renewi/myrenewi@0.1.0 openapi
> orval --config orval.config.ts

node:internal/modules/cjs/loader:1404

Node.js version: 22.16.0
NPM version: 11.4.2

We have a policy that all neccesary packages for a project must be installed with a simple npm i, which makes a lot of sense to me. Until there's a solution, if there's a workaround that doesn't require a global install, I'm all ears 🙏🏻

Btw, this problem looks a bit like issue #326, but that was an old one, and I'm not sure it's totally identical. Either way, it may be related.

Also similar to this AJV issue: #1454

I think others have tried type: module in their package.json or something also to fix it.

[thany]

type: module doesn't help.

In the mean time, an npm ls ajv appears to reveal package versions seem to go awry:

turborepo@0.0.0 C:\Project

    | | | | `-- ajv@6.12.6 deduped invalid: "^8.5.0" from node_modules/ajv-draft-04, ">=8" from node_modules/@stoplight/better-ajv-errors
    | | | +-- ajv-errors@3.0.0
    | | | | `-- ajv@6.12.6 deduped invalid: "^8.5.0" from node_modules/ajv-draft-04, ">=8" from node_modules/@stoplight/better-ajv-errors, "^8.0.1" from node_modules/ajv-errors
    | | | +-- ajv-formats@2.1.1
    | | | | `-- ajv@8.17.1
    | | | `-- ajv@8.17.1
    | | `-- @stoplight/spectral-rulesets@1.22.0
    | |   `-- ajv@8.17.1
    | `-- ajv@8.17.1
    `-- ajv@8.17.1

So it looks like version mismatches (in sub-subdependencies?).

So with that, I've also tried:

• npm i -D avj@latest
• npm i -D avj@^8.5.0
• Putting "overrides": { "ajv": "^8.17.1" } in the package.json (also tried with version 8.5.0)

All to no avail.

We just released 8.0.0-rc.1 which is fully ESM if you would like to retest please and report back.
