Ruby: Chatterbot can't load bot data - ruby

Question

I'm picking up ruby language and get stuck at playing with the chatterbot i have developed. Similar issue has been asked here Click here , I did what they suggested to change the rescue in order to see the full message.But it doesn't seem right, I was running basic_client.rb at rubybot directory and fred.bot is also generated at that directory . Please see the error message below: Your help very be very much appreciated.

I'm assuming that you are trying to load the :data_file passed into Bot.new, but right now you are statically loading a bot_data file everytime. You never mentioned about bot_data in the question. So if I'm right it should be like this :
#data = YAML.load(File.read(options[:data_file]))
Instead of :
#data = YAML.load(File.read('bot_data'))
