Com o RubyStack instalado não precisei instalar mais nada até agora. Para gerar o código Rails para atender as features Cucumber usei scaffold.</p>
<p>Só falta a parte relativa ao login:</p>

Instalei o RubyStack da BitNami no Mac. Testei um hello world no Rails. Sem problemas até agora exceto o costumeiro

Routing Error
No route matches "/test" with {:method=&#62;:get}


que pode ser sanado com um restart do server.
Pretendo começar a testar o Cucumber.

<p>Depois de muitas encrencas com o <a href="http://www.rubyonrails.org/" target="_blank">Rails</a> no Kubuntu resolvi instalar o Mandriva Linux Spring 2007. Já havia tido uma experiência ruim com o Debian antes. Naquela época os problemas foram resolvidos quando optei pelo Mandrake 10.</p>
<p>No Mandriva já veio instalado o Ruby 1.8.5, o irb 0.9.5, rdoc 1.8.1, ri 1.0.1. Infelizmente a documentação não estava no lugar. Para gerá-la é preciso ter os fontes. Como já encontrei o Ruby instalado, provavelmente de uma distribuição binária, deve ter sido esquecida a geração da documentação por quem construiu o pacote binário de instalação. Baixei então os fontes do ruby 1.8.5 para obter os arquivos fontes para gerar a documentação com rdoc. Ao tentar o comando</p>
<p><code>make install-doc</code></p>
<p><em>make</em> também não estava lá. Desisti por enquanto da documentação para fazer a instalação do Rails. Primeiro o RubyGems deve ser instalado. Instalei a versão 0.9.3 do Ruby Gems. O Rails foi instalado com o comando:<br />
<code><br />
gem install rails --include-dependencies<br />
</code></p>
<p>Como já tinha acontecido de outra vez tive que invocar o comando duas vezes pois na primeira ocorreu a mensagem:</p>
<p><code>Could not find rails (&gt; 0) in any repository</code></p>
<p>Na segunda tentativa as mensagens foram de sucesso:</p>
<p><code>Successfully installed rails-1.2.3<br />
Successfully installed rake-0.7.3<br />
Successfully installed activesupport-1.4.2<br />
Successfully installed activerecord-1.15.3<br />
Successfully installed actionpack-1.13.3<br />
Successfully installed actionmailer-1.3.3<br />
Successfully installed actionwebservice-1.2.3<br />

<p>Foi criada uma aplicação ¨Hello world&#8221; para ver se o básico do Rails estava no lugar. Tudo certo. Mas uma vez o Mandriva fez um gol no Kubuntu (Red Hat x Debian) no quesito de instalação do Ruby e do Rails.</p>

<p>O software visa facilitar a penetração no mundo da programação. No momento há apenas uma versão para o Windows. Mas Why promete que logo haverá uma para os <em>OSX </em>e<em> Linux. </em>Uma vantagem que logo fica patente aos se usar o HacketyHack é a disponibilidade de várias bibliotecas que permitem rapidamente fazer alguns programas realmente atraentes logo de início. E por trás de tudo o incrível Camping.<br />
Viva o Why!</p>
