Here is the official Apple Leopard Ruby on Rails overview writeup.

It’s the middle of December, which means a new version of Ruby will be released in just a few days.

Do you spend your time forking and back-porting the library to support your older code base, or do you upgrade your code base to leverage the current Ruby ecosystem?

New major versions (for example, 2.2, 2.3, and 2.4) are traditionally released on December 25 each year.The command that Catfish gave you was which specifically will update the gem binary (which is what you invoke to install or update Ruby gems with the command 'gem').Once you've done that, you can update the Rails framework with "sudo gem update rails".Most likely, this happened because you don't have gcc, the C compiler for most free *nix-based OSs (such as the BSD family that OS X is built on), installed.You can install it (and all the Apple developer tools) by finding your OS install disc and installing the devloper toolkit off of that.Making sure all the layers of your application are secure is just as important as avoiding SQL injection and cross-site scripting vulnerabilities. And sometimes, your hand is forced by a dependency, or a dependency of that dependency.
