jrubyを触っていろいろメモしてみます

rails環境を整える（前提としてjrubyは入っています）

jruby -S gem install rake
jruby -S gem install rails

railsが使えるかテスト

bash-3.2$ jruby -S rails hoge

最新版のrails2-2-2を落としてみたがjruby側のgemの最新バージョンが(1.2.0)のようで利用できなかった
- のでrails2.1.0をインストールし直す

bash-3.2$ jruby -S gem uninstall rails
jruby -S gem uninstall actionmailer -v 2.2.2
jruby -S gem uninstall actionpack -v 2.2.2
jruby -S gem uninstall activerecord -v 2.2.2
jruby -S gem uninstall activeresource -v 2.2.2
jruby -S gem uninstall activesupport -v 2.2.2

jruby -S gem install rails -v 2.1.0
jruby -S rails hoge
jruby -S ./script/about

さらに必要そうなものをインストールしておく

bash-3.2$ jruby -S gem install jruby-openssl
bash-3.2$ jruby -S gem install ActiveRecord-JDBC(JRuby上ではこれがないとうまくdatabaseにつなげないらしい)
bash-3.2$ jruby -S gem install BlueCloth
bash-3.2$ jruby -S gem install RedCloth
bash-3.2$ jruby -S gem install facets(便利utils)
bash-3.2$ jruby -S gem install mongrel
