Have Twurl installed, but I can't access it - ruby

Question

I have installed Twurl but for some reason I still can't use it. I believe I have it installed because it shows up when I type the ls command. Then I am able to navigate to the folder that Twurl is contained in. However, I am not able to go into the Twurl folder because it says it is not a directory. I am able to use the command open twurl, which opens up a seperate terminal window with a lot of information about Twurl, but I can't type anything. One other thing, when I try and run twurl authorize I get this response: twurl: command not found So my question is, how do I go about getting twurl to work now? Such that I can run the twurl authorize command.

I think I might have installed it in two places. I originally used gem install twurl, but then it wasn't working and I was trying some things and used bundler to install at some point too.
