Can't install devise

Hey Sergio Barrera maybe we can try downgrading devise in your Gemfile to a previous version to try and get it to work. In your Gemfile, where it says

gem 'devise'

Try making it:

gem 'devise', '2.2.7'

Then run bundle install again and let us know if it works!

Thank you Jason for checking out on this, I really like this rails tutorial and how you guys presented the material. I changed it to 2.2.7 and now I get this error: An error occurred while installing bcrypt-ruby (3.1.2), and Bundler cannot continue. Make sure that gem install bcrypt-ruby -v '3.1.2' succeeds before bundling. I tried running this gem and it failed: ERROR: Error installing bcrypt-ruby: ERROR: Failed to build gem native extension.

Hi Jason, Also, I already have xcode-tools installed. At this point, I'm now trying to upgrade to ruby 2 / rails 4 and see if can use devise or build anything with rails. Thanks for your help!

I was able to go through the reinstallation of rails to rails 4 manually and now I'm taking the next steps to generate devise views. I find some similarities and some other differences but it's 99% working. I'm right now reading the devise docs because the current user can't sig out. I'll post more updates soon!
