2,950 Pointsawesome_print nil output
I have installed ruby and the awesome_print gem on multiple different hosts and OSes. Each one has the same output when I try to print the contents of a hash:
1.9.3-p385 :012 > ap treehouse { "business_name" => "Treehouse", "location" => "Treehouse Island", "phone_number" => "800-928-2130" } => nil
The first part of the output works fine. But at the bottom of the output, it should spit out the contents of the hash all on one line. Instead is says '=> nil'
How can I fix this?

Treehouse Guest TeacherHey Ben,
This isn't something that can be fixed, exactly. The part that says "=> nil" is the return value of the last statement that is run. When printing something to the screen in irb there is no return value so it returns nil.
