Updating ruby on rails dating 4240 filename
You can see here to learn more about rbenv plugins.You need to initialize rbenv by adding this line in your Git is the version control system of choice for the Ruby community.To illustrate, the probably won't break anything, similar scenarios can happen that involve much larger jumps.(see  below for a larger discussion) In order to avoid this problem, when you update a gem, bundler will not update a dependency of that gem if another gem still depends on it. If bundler needs to update a gem that another gem depends on, it will let you know after the update has completed.Here’s the link: Following the tutorial above recommends using Ruby 2.3.1 and Rails 4.2.6.I use rbenv and ruby-built (both installed with Homebrew) to manage my Ruby versions.
I prefer RBENV because it’s a simpler and lighter weight solution, and together with bundler, it solves the project gemset problem in a more elegant way. rbenv by itself only manages switching ruby versions.
If you followed this guide, you should already have git installed as part of the XCode Command Line Developer Tools.
You may also want to install git separately with homebrew for easier upgrading.
Once installed I couldn’t install Rails (`gem install rails`) because of an error with Nokogiri (sadly, running `gem install nokogiri` threw the same error.) I got Nokogiri up and running by uninstalling a Homebrew keg called ‘xz’ by running `brew uninstall xz`.
This set off a chain reaction that eventually helped me escape the 404th level of hell.
