Today I decided to install all the prerequisites and to show you how I’ve done this, may be for some people it will be useful. And I’m doing it by reproducing the Rails 3.0 tutorial but for Windows.
1. Text editor / IDE
From various IDEs and Unix-style editors like vi or emacs or whatever. I decided to go with a full IDE solution so … the nominees are
- Aptana Studio 2.0 – standalone version
- NetBeans 6.9.1 – ruby version
- RubyMine 2.0 – from JetBrains (creators of Resharper, TeamCity and a lot of other cool software for programmers).
I wanted to go with RubyMine because I already know the difference Resharper brings in my development process, but it’s a 30-days trial, and I don’t want to switch to something new in next few months, so no. I don’t have previous experience with Aptana Studio, and may be I will try it some day, but I had a pleasant experience with NetBeans so for now I will go with that.
Ruby community uses intensely a version control system called Git, so I will install it too. For windows part it is very simple. You go to http://code.google.com/p/msysgit/. Click “Downloads” and choose current version Git.exe installer.
Install process is Windows-style - very simple as well. We don’t have to manually compile something or edit, everything goes quite simple.
3. Installing Ruby
First we need to be sure that our system doesn’t already has Ruby installed. Let’s try it.
C:\Users\user_name>ruby -v 'ruby' is not recognized as an internal or external command, operable program or batch file.
Well looks like I don’t have it installed. Not a problem. First we’ll install Ruby 1.8.7 which works well with Rails 2.3. We’ll go to Download Ruby page search for “Ruby on Windows” section and select Ruby 1.8.7-p302 RubyInstaller. Installation goes smoothly. I associated my *.rb files with ruby and added Ruby executables to my path.
Now we see this in our command line:
C:\Users\user_name>ruby -v ruby 1.8.7 (2010-08-16 patchlevel 302) [i386-mingw32]
4. Installing and using Pik
What is Pik? Pik is a Windows alternative to Ruby Version Manager (RVM) which allows us to have multiple Ruby versions installed at the same time, as I said before we need Ruby 1.8.7 to work with Rails 2.3 and Ruby 1.9.2 to work with Rails 3.0.1 and Pik will help us in dealing with this. You can download Pik from github. Also be sure to check its Wiki page “Usage”.
Now when we run the first time pik it adds the default Ruby path which right now points to version 1.8.7. I also set Pik default install directory to “C:\Rubies” and I also show how to add an existing ruby installation to pik with the “add” command.
C:\Users\user_name>pik ** Adding: 187: ruby 1.8.7 (2010-08-16 patchlevel 302) [i386-mingw32] Located at: C:\Rubies\Ruby187\bin Usage: pik command [options] To get help with a command pik help (command) To list all commands and descriptions: pik help commands -V, --version Pik version -d, --debug Outputs debug information C:\Users\user_name>pik config installs="C:\Rubies" C:\Users\user_name>pik add C:\Rubies\Ruby-1.9.2dev-p3-i386-mingw32\bin ** Adding: 192: ruby 1.9.2dev (2010-05-31) [i386-mingw32] Located at: C:\Rubies\Ruby-1.9.2dev-p3-i386-mingw32\bin
Next I show how to install a Ruby version using “install” command. In my particular case I installed IronRuby specifying the version, and then not specifying it. When you don’t specify it then Pik downloads the latest version. (although at the moment the latest version of IronRuby is 1.1.1, don’t know what is wrong there). Than I show how to list all the available Rubies installations (note that * marks the default ruby used at the moment), how to remove a Ruby install from Pik management, and how to switch to another Ruby installation.

The only thing that I can’t find is an alternative to RVM –create command which is often convenient to create separate gemsets.
5. Installing and using RubyGems
UPDATE: After installing any version of Ruby you already should have RubyGems installed. You can check it up by using “gem –v” command. I talk about installing RubyGems here just because I was having errors with default installation of gem.
After everything done I already have gems installed but it has some errors so I will download the latest version from here. After that you unpack it somewhere cd into its directory and say
Now gems should be installed. Next thing you could do is see what is your Gems environment with “gem env” command, or see the gems sources with “gem sources” command. Finally you could do “gem list” for list of local gems, “gem list –r” for remote gems, and “gem list STRING” which will bring you the list of gems starting with string.
6. Installing Rails
Now having Gems installed it’s really easy to install Rails. You should just say
gem install rails
gem install rails --version 3.0.1
Now everything should be prepared and installed. You can verify it by writing “rails –v” and have the rails version.
Well that’s a lot of things to do, especially if you’re used already with Windows way of installing things. Hope this post will help someone.
Next time we’ll do our first application in RoR (Ruby on Rails), so stay tuned!
