#WDI Installfest

We are going to install the tools necessarily to program with Ruby and Rails on your computer.

If you are unsure or run into problems during installation, don't worry; We will finish up any of the loose ends on Installfest.

##Verify your install If you have already experimented with ruby or rails before, verify your versions are correct for this upcoming class.

If you can see the correct version numbers when you run the commands in Terminal below, you are good to go.

Verify you are running 2.0+ of ruby

ruby -v

Verify you are running version 4 of Rails

rails -v

If not, continue with the instructions to get your environment going. Run these again after you're done to ensure everything is working properly.

###Brew Doctor Run brew doctor in your Terminal to let you know if the install was successful. It will give you tips on what you can do to correct any system wide issues. If you do have any problems, resolve them. If you have any questions or unsure, we will take care of these issues during Installfest.

You may need to edit your ~/.bashrc to have include the path to homebrew, if brew doctor returns any warnings.

bash echo 'export PATH="/usr/local/bin:/usr/local/sbin:~/bin:$PATH"' >> ~/.bash_profile

#Windows Users

Ruby Installer:

The install on Windows is actually very with the bundle from rubyinstaller.org

Just be sure to grab the 2.0.0 version, as that will be the version we will be using in class. This will set up your environment and you can start running ruby files right away.

To install rails, run the following command gem install ruby

**Extra command line tools: **

We will be using the command line a lot here. On Windows I also like to install gow. Gow is a bunch of unix command line tools ported to Windows. It will make it easy to follow in class with the same commands as your Mac buddies.
