[Bug] Error: EISDIR: illegal operation on a directory, symlink

[RR2pao]

Describe the Bug

Hello OHIF Team! I was following the installation steps (https://docs.ohif.org/development/getting-started/), when I got this error at "yarn install":

error Error: EISDIR: illegal operation on a directory, symlink 'A:\temp\Viewers-master\addOns\externals\dicom-microscopy-viewer' -> 'A:\temp\Viewers-master\node_modules\@externals\dicom-microscopy-viewer'

What I already tried:

• run terminal as administrator
• delete node modules folder, delete yarn cache
• installation with earlier yarn version

Details of my setup: OS: Windows 11 user: admin

node --version v20.14.0 npm --version 10.7.0 yarn --version 1.22.22

I was cloning the current master branch of OHIF viewer.

Steps to Reproduce

0. clone master branch
1. yarn install

The current behavior

yarn install throws the following error: error Error: EISDIR: illegal operation on a directory, symlink 'A:\temp\Viewers-master\addOns\externals\dicom-microscopy-viewer' -> 'A:\temp\Viewers-master\node_modules\@externals\dicom-microscopy-viewer'

The expected behavior

yarn install should install dependencies.

OS

Windows 11

Node version

v20.14.0

Browser

Chrome 126.0.6478.126

This is strange. Can you clone the repository in a new location and check if the issue persists with a fresh clone?

Finally figured it out. The repository was cloned to a virtual drive encoded with VeraCrypt. The format was exFAT, thats where this bug occured. I created a new VeraCrypt volume with NTFS, and it works fine.
