I am new to Ruby on Rails. Recently, I downloaded and installed the
InstantRails in the D:\ drive of my system. Now I wanted to try some
small examples in ‘irb’, so I created a file “testapp.rb” and in that
pasted a code like this:
puts “sample program”
myclass = sample_class.new
Now when I give command (To run the application) “ruby testapp.rb” ,
I get this error “NameError: undefined local variable or method
`testapp’ for main:Object”. I believe, the irb is not able to
recognize any .rb file. Can anybody help me with this?
location of irb - D:\RoR\ruby\bin
location of testapp.rb - D:\RoR\ruby\bin
Many thanks in advance!
