I have two versions of Ruby installed (1.8 and 1.9). ï¿½When starting a

can set, but I don’t know what it is.
What OS are you running, and how did you install both versions?
I am using Windows 7 Professional (64-bit). I previously had Ruby 1.8.6
installed using the old 1-click installer. I then installed Ruby 1.9
using the windows installer found at RubyIntaller.org.
The Ruby 1.9 is automatically installed in a different directory
(C:\Ruby19 instead of C:\Ruby) so the two installs are independent. I
have made Ruby 1.9 the default (it is the only one in my Path). So, as
was suggested earlier, to run a Ruby 1.8 program I just issue the
command ‘C:\Ruby\bin myprogram.rb’. To run a Ruby 1.9 program I just
do ‘ruby my program.rb’
It is working great. Thanks everyone!
