Question

I’m relatively new to Ruby on Rails. I need to use an iCalendar event in my web app.

First, I installed the iCalendar gem as below:

gem install icalendar

I then ran the gem list command, and it indicated the gem was installed. However, I can’t actually use the gem anywhere. If I do:

event = Icalendar::Event.new

I get the error that iCalendar is an uninitialized constant.

If I try to include iCalendar within a class as below:

require 'icalendar'

I get the error:

MissingSourceFile:  no such file to load -- icalendar

Any suggestions?

Does the path to ruby on top of /usr/bin/gem match the output of which ruby? If not, make sure they match or give the explicit path to the one in /usr/bin/gem.
