Joined problem with nodejs/npm v6 macOS 11.1 and the docker

[dominikj111]

I got a problem with my npm install command where I'm getting issue described here.

I'm looking for a correct direction to solve this problem, but not sure what forum to select to report it, therefore I'm here with my next question.

npm install is working in the docker container (ubuntu:focal) and in the VirtualBox (Windows 10). But not in the shared nor mapped folders. The project must be placed in the inner virtual folder.

I don't think that it is the permissions issue as I set the project to 777 for all chmod -R 777 project.

npm v7 is working, but I've to use v6.

What can cause that the npm failing if running upon shared/mapped folder?
