Dear all

I try to run ri String in my Window command prompt, it show the  
following error

‘less’ is not recognized as an internal or external command, operable  
program or batch file.

Is the ri not support for window? How can I fix it?

Thank you very much

Valentino

Try setting environment variable PAGER to more, e.g.

set PAGER=more

No idea whether that helps. I can’t test it because I don’t use the  
Windows distribution.

Kind regards

How did you install Ruby on Windows?

I’m using the One Click Installer (Ruby 1.8.6), and “ri String” works  
just fine (on XP and Vista).

Hope this helps,

Wayne
