Probably, you have no hope as you have it, you are still trying to use rails 4.2.5 which is hugely different to 2.3.5 Installing a specific gem version is easy. For example gem install <name> -v n.n.n Not sure whether for Rails you can just remove the gem versions above and install the 2.3.5 ones or if you will also have problems with the support tools that come with rails being of a later flavour You might also have issues with the version of Ruby you have installed. I don't know which versions of Ruby 2.3 will run with. The nicest way to do it would be to use rvm, which lets you run multiple versions of gems from what are called gemsets, then you can just make the right versions of gems available to your app. Rvm will also allow multiple versions of ruby. But really you are on a massive learning curve, you need someone who knows what they are doing or you will be splashing about in the swamp for a long time.
