Error parsing parsing audio file for id3 tag information with taglib-ruby

Question

I'm trying to get ID3 file information from an audio file using taglib-ruby gem like so ...

# Load a file
TagLib::MPEG::File.open path_to_audio_file do |fileref|

  unless fileref.null?

    data = {}
    data['tag'] = fileref.tag
    data['properties'] = fileref.audio_properties
  end
end

But I'm getting this error (below)

Wrong arguments for overloaded method 'File.new'.Possible C/C++ prototypes are: File.new(TagLib::FileName file, bool readProperties, TagLib::MPEG::Properties::ReadStyle propertiesStyle) File.new(TagLib::FileName file, bool readProperties) File.new(TagLib::FileName file) File.new(TagLib::FileName file, TagLib::ID3v2::FrameFactory *frameFactory, bool readProperties, TagLib::MPEG::Properties::ReadStyle propertiesStyle) File.new(TagLib::FileName file, TagLib::ID3v2::FrameFactory *frameFactory, bool readProperties) File.new(TagLib::FileName file, TagLib::ID3v2::FrameFactory *frameFactory)

Any ideas what could be causing this error?
