You're probably trying to open a directory (. and .. in 'text/'). Try
one of the two examples below:

campershash =3D {}
Dir.entries("text").each do |textfilename|
    # Don't know why you're using four chop's - but I've replaced them
    # with 'strip' to make the example more readable.
    campershash[textfilename.strip] =3D=20
        File.read(File.join("text", textfilename)) if File.file?(textfilena=
me)
end

or

campershash =3D {}
Dir["text/*"].each do |f|
    campershash[f.strip] =3D File.read(f)
end
