Error: undefined method `read' for PDF:Module

[s2t2]

I'm trying to use this gem to parse a PDF file that exists on my local file system. When I follow the instructions, this gem doesn't work. Please advise!

require "origami"
include Origami

local_file = File.join(File.expand_path("../../tmp", __FILE__), "my_report.pdf")

pdf = PDF.read(local_file)

#> NoMethodError: undefined method `read' for PDF:Module

Versions:

• origami 2.0.2
• ruby 2.2.3p173

I am unable to reproduce this problem with the 2.0.2 gem on any versions of Ruby.
Are you sure you don't have another library defining its own version of a PDF class or module ?

Is the problem present if you use explicitly call Origami::PDF.read(local_file) ?
