Installing Ruby on Rails in Debian: The Definitive Guide

Install RubyGems and SQLite 3 development files:

sudo apt-get install rubygems libsqlite3-dev

If you attempt to install gems, you will get into trouble:

ERROR: While generating documentation for <XXX>...

To make gem work properly, you should add gem's path to bashrc:

echo "export PATH=/var/lib/gems/1.8/bin:$PATH" >> .bashrc

Then install Rails, Thin[1] and Rake:

sudo gem install rails thin sudo gem install -v '~> 0.8.7' rake

Create a demo project:

rails new blog && cd blog

Rake 0.9.0 will mess up everything!!!

rake aborted! undefined method `task' for #<Blog::Application:0x...>

To solve this problem [2] :

echo "gem 'rake', '~> 0.8.7'" >> Gemfile

Install dependencies:

sudo bundle install

Create databases:

rake db:create

Start the web server:

thin start

On remote machine, run:

sensible-browser http://<hostname>:3000

How to Install CoffeeScript in Debian

Introduction to CoffeeScript

CoffeeScript is a little language that compiles into JavaScript. Underneath all of those embarrassing braces and semicolons, JavaScript has always had a gorgeous object model at its heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.

Installation

Run as root:

apt-get install nodejs -y wget \ github.com/jashkenas/coffee-script/tarball/master \ --no-check-certificate -O coffee-script.tar.gz tar zxf coffee-script.tar.gz rm coffee-script.tar.gz cd jashkenas-coffee-script* bin/cake install ln -s /usr/local/bin/coffee /usr/bin/coffee

Usage

Compile a directory tree of .coffee files into a parallel tree of .js, in lib:

coffee -o lib/ -c src/

Watch a file for changes, and recompile it every time the file is saved:

coffee --watch --compile experimental.coffee
