This is my error screen after trying to execute the command. I've tried to uninstall and reinstall readline and that did not help. I am just learning rails and do not 100% know what I am doing (just following a guide) so this type of error is past my understanding. Thanks!
Might not be related, but I had the same thing happen to me today.
I had a fully-functioning Ruby 2.3.1 working fine this morning. In my case, Ruby was compiled and installed by ruby-build and managed by rbenv.
At one point today I updated Homebrew with
brew cleanup --prune=30
brew update
brew upgrade
One of the formulae upgraded was readline 7.0:
$ brew info readline
...
/usr/local/Cellar/readline/7.0 (45 files, 2M)

Shortly afterwords I found that my readline support for Ruby had become completely broken. I saw errors just like yours:
/Users/mbrictson/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/pry-0.10.4/lib/pry/config/default.rb:151:in `require': dlopen(/Users/mbrictson/.rbenv/versions/2.3.1/lib/ruby/2.3.0/x86_64-darwin15/readline.bundle, 9): Library not loaded: /usr/local/opt/readline/lib/libreadline.6.dylib (LoadError)

The solution was to completely delete my Ruby installation and recompile it:
rm -rf ~/.rbenv/versions/2.3.1
rbenv install 2.3.1
I know you are using rvm and not rbenv, but perhaps the solution in your case is similar: delete your Ruby installation and re-install it using rvm.
A really fast and quick solution is to add rb-readline to your Gemfile. (In case the other solutions don't work and you want to move on until you have time to address the issue. I know it this is not ideal but it is a working solution.)
In the GemFile:
group :development do
gem 'rb-readline'
end
Now, just bundle install. I found this solution on Option 4 at (https://github.com/guard/guard/wiki/Add-Readline-support-to-Ruby-on-Mac-OS-X) I hope it helps.
