I installed ruby from Ubuntu a week ago but it seems that I have version
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-linux]
The book ‘Ruby P.ming Language’ I am studying (very good is from
2008 and talks about 1.9 (versus 1.8). Do I need to re-install?
In case this gets lost in the plethora of links for this issue (and
you don’t use RVM): Substitute the book’s use of ruby and irb with
ruby19 / irb19.
A method of solution is perfect if we can forsee from the start,
and even prove, that following that method we shall attain our aim.
