npm ci and local packages issue

What I Wanted to Do

I want to run “npm ci” without any errors just like i run “npm install”

What Happened Instead

Symlinks are not setup correctly and throws error that the source folder exists already.

Reproduction Steps

Set up a monorepo with packages dependent on each other.
Add local packages as dependecies in package.json with a local path (file:…/another-repo)
