Node.js v21.7.1

Creating a new directory and running:
npm init -y
npm install -d is-ci
Does not resolve the issue and returns the same error.

Running:
npm list is-ci
Returns:

vscode-theme@1.0.0 /root/Workspace/Projects/vscode-theme
├── is-ci@3.0.1
└─┬ yo@5.0.0
  └─┬ update-notifier@5.1.0
    └── is-ci@2.0.0

Can anyone help me resolve this error so I can generate projects with yeoman.
Thanks
