Learning Rails: Installing Rails, Part 2 – Windows

Table of Contents

Last time, I installed Rails on the Debian box and had some trouble, but I got through it. This time, I’m going to install Rails on the Windows box.  This is my laptop that I have with me most often, so I need to develop from it, too.

Installing Ruby and RubyGems

To begin, I need Ruby on the machine, and luckily there is a Windows installer available. The RubyInstaller project is:

…a self-contained Windows-based installer that includes the Ruby language, an execution environment, important documentation, and more.

That’s handy. I download the latest RubyInstaller from here and run it.  I make sure to check Add Ruby executables to your PATH so I can use ruby and gem from the command line.

When it finishes, I open a command prompt to make sure it installed correctly.

C:\Users\Miller>ruby --version
ruby 1.9.2p290 (2011-07-09) [i386-mingw32]

RubyInstaller also installs RubyGems automatically, but it’s an older version.

C:\Users\Miller>gem --version
1.7.2

I update to the latest version using the gem update --system command.

C:\Users\Miller>gem update --system
Updating rubygems-update
...snip...

C:\Users\Miller>gem --version
1.8.10

Installing Rails

The easiest way to install Rails is with RubyGems.
