Ich habe Ruby on Rails basierend auf den Anweisungen der edX Online-Klasse installiert.
Hier ist eine Liste der Terminalbefehle und gegebenenfalls der entsprechenden Ausgabe:
$ sudo apt-get install ruby1.9.1
Installation erfolgreich
$ wget http://production.cf.rubygems.org/rubygems/rubygems-1.8.24.tgz
$ tar zxvf ruby-1.8.24.tgz
$ cd ruby-1..8.24
$ sudo ruby setup.rb
RubyGems 1.8.24 installed
== 1.8.24 / 2012-04-27
* 1 bug fix:
* Install the .pem files properly. Fixes #320
* Remove OpenSSL dependency from the http code path
