If you can't find it, open "Run", type "cmd", and hit ENTER. It should open up the command line briefly, and then shut down again. ![]() To install Devkit, open up the folder and locate the file, "dk.rb". Without it, Windows gems installation is a pain. The Ruby Devkit makes gems build on Windows. I chose the hard-drive's root directory, so it is shown beside the "Ruby192" folder. Now, open the self-extracting devkit package. Ruby is now installed in your hard drive's root directory. Make sure to select both checkboxes (regarding the file extension and executables). I chose the version at the top of the list (Ruby 1.9.2, at the time of this writing). The alternative is to individually install Ruby and Gems, which is much harder.The first step is to download the package from (also download the newest devkit, which is shown lower on the page). Through Gems, you can easily install Rails. It comes with Ruby and Gems packaged together. Installation NOTE: I used Ruby Installer in this example. However, I'd recommend that you still read this post so that you can become familiar with Rake, Gems, etc. Gems - Ruby addons like libraries in other languages.īundle Installation PackageIf you don't want to mess with installing the components individually, then you can just install the Rails Installer package.Rails - The most widely used Ruby framework used for web development.Ruby - The base computer programming language from which the Rails framework is built.Definition ListHere are some definitions that you will help you to better understand terms used within these instructions. Now I'll share with you how I installed a Ruby on Rails development environment on my Windows computer. I had my own problems installing it since most of the resources I found were either written from Mac perspective or old Ruby versions. Unfortunately, installation is what discourages some people from learning a language. The Rails framework extends Ruby to expedite the task of building web applications. The goal of Ruby is to make the code closer to spoken language and less of curly braces and semi colons. Once I started to read about it, it became quite obvious why. Note how there is a parent element that contains three elements, one for each color.Ruby on Rails (RoR) is a revolutionary web programming language. To illustrate, here is the code for an unordered list of colors: One thing to note about HTML lists is that they are structured such that, for a given list, list-item elements ( ) that represent the items of the list are nested inside a parent list element ( or ) that represents the list as a whole. HTML includes elements for displaying unordered lists ( i.e., bullet lists) and ordered lists ( i.e., numbered lists), and they are well explained in this W3Schools page. HTML includes a paragraph element ( ) for defining the paragraph structure of a page, and it is well explained on this W3Schools page. For example, an element should never be followed by an element, unless that element somewhere in between them. You can also use, ,, and tags to further subdivide your content.The tag is usually used for the first level of subheadings.The tag is usually used for page titles and only once per page.Here are a few additional things to note about HTML heading elements: HTML includes a set of heading elements (, , etc.) for structuring pages into sections, and they are well explained on this W3Schools page. For convenience, I list below the some of the most basic HTML elements used (without explanation) in the demos. The Demos-n-Deets assume a basic understanding of HTML.
