How to find which version of node is used/considered by pnpm? (related to ERR_PNPM_UNSUPPORTED_ENGINE)

by

I run pnpm install and got this error:

$ pnpm install
Lockfile is up to date, resolution step is skipped
 ERR_PNPM_UNSUPPORTED_ENGINE  Unsupported environment (bad pnpm and/or Node.js version)

Your Node version is incompatible with "/dependency-cruiser/16.0.0".

Expected version: ^18.17||>=20
Got: v18.5.0

This is happening because the package's manifest has an engines.node field specified.
To fix this issue, install the required Node version.

I can’t find where the version 18.5.0 came from (related to Got: v18.5.0). That version is not installed. In my opinion, I satisfy that criteria with my actual node version (v20.10.0, see below).

I’m on Windows 10, with Git Bash. I have installed pnpm with PowerShell command iwr https://get.pnpm.io/install.ps1 -useb | iex.

Here are versions of pnpm and node:

// actual version of pnpm
$ pnpm --version
8.14.1

// actual node's version
$ node --version
v20.10.0

// all my node's versions:
$ pnpm env list
  18.19.0
* 20.10.0
  21.6.0

Could it be that a package need 18.5, and this is what Got is using? Because my first impression is that Got is detected by the node --vesion in use. But, it could hardly be that, because 18.5 is not installed.

EDIT:
Strangely, if I remove the lock file, it works, but the next pnpm install command fails with error shown above.

$ rm pnpm-lock.yaml 
$ pnpm install
