Missing dependency - pry

[oscarcarlsson]

I've just installed LRF on my machine, and after trying to run it I was met by an error message:

Tested both on 2.4.1 and 2.3.4, printout is identical for both.

The current workaround: gem install pry

Thanks for the heads up. FYI LRF needs a major overhaul and currently does not work on my machine. Should probably update the README to reflect that, or just get around to it this weekend.

Ah, I was trying to figure out what wasn't working with my setup but I guess it won't work no matter what I try then. I don't know any ruby so can't help you with the overhaul :(
