Ruby: irb doesn't work on Windows

Question

I\'ve installed Ruby 1.93 in my windows 7 PC using Ruby 1.9.3-p194 one click installer. I can use ruby command to interpret files, but when I type irb

Answer 1

I'd suggest to use DevKit. I have 64-bit Windows 7 and ruby 1.9.3-p125, and everything works smoothly with DevKit.

d:\>systeminfo | findstr /B /C:"OS Name"
OS Name:                   Microsoft Windows 7 Enterprise

d:\>ruby -v
ruby 1.9.3p125 (2012-02-16) [i386-mingw32]

d:\>irb
irb(main):001:0> 2+2
=> 4
irb(main):002:0> exit
