install-peerdeps `ERR undefined` on windows

Installing ESLint configs using install-peerdeps fails on windows 10/11 Running the code below produces the error as seen in the screenshot

npx install-peerdeps@latest --yarn --dev @upleveled/eslint-config-upleveled

OS: Windows 10 and also tested on windows 11 Node Version: 18 CLI: Hyper

Steps to reproduce Failing project reproduced in this repo

Things I have tried Running the config with a specific install-peerdeps version Running the config with no version number Downgrading nodejs None seems to have helped

After seeing this error numerous times from different students in the bootcamp, it appears that this ERR undefined will happen if there is any error associated with the underlying command.

So, what I understand is:

1. This is actually not the real error message, it is obscuring the real error message
2. It doesn’t have to do with some particular error - it happens with all errors (gut feel says it’s probably related to accessing some undefined property internally in install-peerdeps@3)
3. This does not happen in install-peerdeps@2

Same error with me trying to use with my private repo. The solution to display the real error was to use v2 as mentioned above by @karlhorky

npx install-peerdeps@2 --dev <package-name>
install-peerdeps v2.0.3
ERR That package doesn't exist. Did you mean to specify a custom registry?
