Install NODE-RED offline

Hello,
How do I install Node-RED on computers that do not have internet access?
What procedures should I do to install it?
I already managed to install it at home, but not at school.

I have the folders: npm and npm-cache, created when installing at home. Do I use these folders to install on another computer?
