Install Ruby 1.9.1 on Debian#

NOTE: This Installation works, but obviously it is still buggy.
When I tried to migrate an application I had several issues and finally an internal server error. I finally used the basic installation then. Use it also as template for this installation, but follow my instructions here.

1. Consider to install Paco before.

2. Install Ruby

• Look at ftp://ftp.ruby-lang.org/pub/ruby/ for the latest stable version
• Download with wget like and "tar xzf"

wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.1-p243.tar.gz

• Install

./configure
make
paco -lp ruby-1-9-1 'make install'

• check status

ruby -v
=> ruby 1.9.1p243 (2009-07-16 revision 24175) [i686-linux]

3. Ruby 1.9.1 comes with rubygems, so ignore installing rubygems

gem -v
=>1.3.1

4. Install Rails (this will take a while)

gem install rails
=>Successfully installed rake-0.8.7
Successfully installed activesupport-2.3.4
Successfully installed activerecord-2.3.4
Successfully installed rack-1.0.0
Successfully installed actionpack-2.3.4
Successfully installed actionmailer-2.3.4

5. My specialty: Install will-paginate: http://wiki.github.com/mislav/will_paginate/installation

6. Install mysql connector

apt-get install libmysql-ruby
apt-get install libmysqlclient15-dev
gem install mysql

7. Update system

gem update --system

8. Make a test app

rails TestApp -d mysql

Migrating an existing app made problems, here are some hints:

rake rails:update:application_controller 
rake tmp:clear
# encoding: utf-8

Uninstall#

gem uninstall rails

If paco is used

 paco -r <your ruby package name>
