Railsのインストール
以下のサイトを基にRuby on Rails（以下、Rails）をインストールします。

Railsのインストール（ruby-1.9.2-p136）
Railsはgemとして提供されているので、gemのコマンドでインストールします。
最新バージョンのgemは次のコマンドでインストールします。
gem install %gemの名前%
Railsをインストールするということは、「rails」というgemをインストールすることになるので、
最新バージョンのRailsは次のコマンドでインストールします。
gem install rails
実際にインストールしてみます。
まずはRVM管理下にある「ruby-1.9.2-p136」の環境にインストールしてみます。

「rails (3.0.4)」がインストールされました。
他にも色々インストールされたようです。
それぞれについては追々みていくことにします。
Railsのインストール（ruby-1.8.7-p330）
同様に、RVM管理下にある「ruby-1.8.7-p330」の環境にもインストールしてみます。
rubyの環境をRVM管理下の「1.8.7」に切替えます。
goh:~ goh$ rvm use 1.8.7 Using /Users/goh/.rvm/gems/ruby-1.8.7-p330 goh:~ goh$

gemのインストールは成功したようですが、ri、RDocのインストールでは、いくつか失敗しているようです。
インストールされたgemを確認してみます。
goh:~ goh$ gem list *** LOCAL GEMS *** abstract (1.0.0) actionmailer (3.0.4) actionpack (3.0.4) activemodel (3.0.4) activerecord (3.0.4) activeresource (3.0.4) activesupport (3.0.4) arel (2.0.9) builder (2.1.2) bundler (1.0.11) erubis (2.6.6) i18n (0.5.0) mail (2.2.15) mime-types (1.16) polyglot (0.3.1) rack (1.2.2) rack-mount (0.6.14) rack-test (0.5.7) rails (3.0.4) railties (3.0.4) rake (0.8.7) thor (0.14.6) treetop (1.4.9) tzinfo (0.3.26) goh:~ goh$
「1.8.7」の環境にも「rails (3.0.4)」がインストールされました。
riもRDocもドキュメントだということはわかるので、Railsの動作に影響はないと思いますが、
-
- どうやって使うのか
- どうやって修復するのか
は別の機会に確認します。
