How to I launch a ruby script from the command line by just its name?

Question

On windows, I can run my ruby script like this:

> ruby myscript.rb

but I want to set things up so that I can just do this instead?..

Answer 1

None of the command line solutions worked for me on Windows 10. I've previously used the Windows GUI to open .rb files using Notepad++. When I run

script.rb

in the command line, it just opens Notepad++ with the .rb file (even after the command line fixes).

What solved the issue for me was

1. Right click a .rb file
2. Click "Open With"
3. Click "Choose another app"
4. Click "More apps"
5. Click "Look for another app on this PC"
6. Open the ruby.exe interpreter from my ruby installation.
