Multiple errors on capistrano deploy

Question

Hi so I'm trying to deploy using Capistrano to a server, on the server I have rails bundler and everything else installed, however, here is the Capistrano log

https://gist.github.com/benbagley/cf8233aaa0c5adac0fa09f2194fc6890

Here is the trimmed down version of just the errors:

If you have a Gemfile in your project you can try add bundle install into one of the deploy steps and have that install all the required ruby gems. Also as the rake version is mismatching you need to update the Gemfile and Gemfile.lock to make it matches the required version first.
