RoR Setup

From MashupCamp

Before the session, it would be helpful to download and install the necessary software:

• Ruby One-Click Installer
• Rails: From a command prompt type: gem install rails --include-dependencies
• MySQL (Use configuration defaults)
• MySQL GUI editor

Alternate Setup

These packages install everything you need in one step, but are not standard setups (at least for Instant Rails)

• Windows: Instant Rails
• OS X: Locomotive
• OS X: build from source: Hive Logic Blog - This post has a great step by step build process which has exact version numbers and pre-requisites needed (and how to build them) as well as the best install order

For other ways to install Ruby or for non-Windows OSes, see:

• Ruby on Rails Downloads

Check Path

The latest Ruby One-Click Installer (1.84-19) doesn't seem to put Ruby in the path. To check this, start a command window and type "irb". If an error occurs, follow these instructions:

1. Start -> Control Panel
2. System -> Advanced -> Environment Variables
3. System Variables -> Path -> Edit
4. To the end of the existing path, add a semicolon ";" and then "c:\ruby\bin" then save.

To see if the changes work, close the command window and then re-open it (to load the new path) and try "irb" again.
