I am trying to create gem using bundler. This gem requires pp gem to make 'pretty print'. I have require 'pp' at the top of the source and after that I use pp where needed. However, a runtime error occurs.
D:/PRJ/git/smde/vendor/bundle/ruby/2.5.0/gems/pp-0.1.1/lib/pp.rb:1:in `require': cannot load such file -- pp/room (LoadError)
There is no room file in lib/pp directory in pp gem. Why?
What is more interestingly, pp gem works well when I start my gem scripts directly, i.e. "ruby myscript.rb". The lack of pp/lib/room is not essential.
The "pp" gem is not required for using pretty print. That gem is related to Campfire, which does have the concept of a room. See https://www.rubydoc.info/gems/pp/0.1.1/Pp
Pretty print is available to you without requiring anything: notice if you run irb, you can immediately type
pp "something"
And it will print as you want.
