when I typed in $ ruby -v the output appeared as below:
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.0]
In the past, I used to see the output as:
ruby 1.9.3
Why is my ruby version appearing with more data now? I am new to programming and am wondering if I messed up my computer. Help! Thank you in advance!
Chances are, you upgraded your Ruby installation somewhere along the line (or your system package manager did). It's very unlikely that you messed anything up.
