Ruby関連（gemとかrailsとか）のメッセージの対処

gemとかRailsとか実行しようとすると、以下の警告メッセージが必ず表示されてた。

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/universal-darwin13/rbconfig.rb:212: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777

「PATHの/usr/local/binが、mode040777になってて、書き込めて危ないよ。」ってことなので、/usr/local/binディレクトリを見ると、確かに権限が777になってた。

$ sudo chmod 744 /usr/local/bin

変更したあと、もう一度確認すると、今度は以下のメッセージが。

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/universal-darwin13/rbconfig.rb:212: warning: Insecure world writable dir /usr/local in PATH, mode 040777

/usr/localもかよ！ってことで、また権限変更。

$ sudo chmod 744 /usr/local

今度はメッセージが出なくなった。めでたしめでたし。

Rails奮闘記 サーバ立ち上げまで

だいぶ期間が空いてしまったけど…早速使ってみる。

小遣い管理システム作るぞー。

（railsのmanページに乗ってたURL：http://guides.rubyonrails.org/getting_started.htmlを参照した）

まず、ブログ領域を作成。

$ rails new testmoney

create  .gitignore
create  Gemfile

次はbundler(Gem 管理ツール)のセットアップ。

$ bundle install 
Fetching source index for http://rubygems.org/
Using rake (0.8.7) 
Using abstract (1.0.0) 
Using activesupport (3.0.1) 
Using builder (2.1.2)

Using activemodel (3.0.1) 
Using erubis (2.6.6) 
Using rack (1.2.1) 
Using rack-mount (0.6.13) 
Using rack-test (0.5.6) 
Using tzinfo (0.3.23) 
Using actionpack (3.0.1) 
Using mime-types (1.16) 
Using polyglot (0.3.1) 
Using treetop (1.4.8)

Using arel (1.0.1) 
Using activerecord (3.0.1) 
Using activeresource (3.0.1) 
Using bundler (1.0.3) 
Using thor (0.14.3) 
Using railties (3.0.1) 
Using rails (3.0.1) 
Using sqlite3-ruby (1.3.1) 
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

次にrakeコマンドで、データベースを作成。

$ rake db:create                                       [~/testmoney]
(in /Users/***/testmoney)
/Library/Ruby/Gems/1.8/gems/bundler-1.0.3/lib/bundler/runtime.rb:132: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777

これで準備完了！（さすがrails！！）

サーバを起動してみる。

$ rails server
/Library/Ruby/Gems/1.8/gems/railties-3.0.1/lib/rails/script_rails_loader.rb:11: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777

無事にサーバが見れてよかったです。

次回は、いよいよチューニング！

# ここまでは、マニュアル通りだもんね…。

Railsに再挑戦（立ち上がり編）

仕事の関係でRubyに触れる機会が増えた。
しばらく使う羽目になりそうだったので、学生の頃に生半可に教わったRailsに再挑戦しようと思う。

Ruby on Railsとは（勉強的な意味で）

Railsは、一言で言えばWebアプリケーションのフレームワーク、だと考えている。（Wikipediaにまんま書いてあったｗ）

MVC(Model-View-Controller)アーキテクチャの考えを軸として設計されている。それぞれ、意味は以下のとおり。

• データや手続きを表現する要素
• モデルのデータを取り出し、ユーザに最適な形で表現する要素
• ユーザの入力に対して応答（処理）する要素

…調べだしたら色々書きたくなったけど、まとめるのが大変そうだから、勉強系は次回に持ち越しｗ

今日はインストールとセットアップまで！

Railsのインストール

まずはインストールとセットアップなんだけど、Snow LeopardにはRailsがインストール済みな状態みたい。

$ rails -v
Rails 2.3.5

念のため、Railsのアップデート。

（root権限で実行するように。ここだけに限らないけど。）

と、早速エラーがｗ

$ sudo gem update rails

（途中でSuccessfully installed rails-3.0.0って出てるから、エラーじゃないのかも…）

しかし、libが無いって何だろう…？

もしかしてRailsのインストールが怪しい？と思って、再インストールをしようとしたら、

$ sudo gem install rails

同じかよ！

ちょいと調べたら、Rubyのバージョン（今が1.8.7）が最新じゃないからかも…

アップデートしてみた。

libversionが定義されてないとか、怪しいエラーっぽいけど、これでもう一回トライ。

…変わりませんでした…。明日、再調査します。

こーやってハマることが何だか懐かしいｗ

ちなみに、このgemsってのがよく分かってなかったので調査（メモ程度だけど）。

（RubyGemsはRubyの標準パッケージ管理システムで、Railsをはじめとした色々なパッケージの管理を行うことが可能。）

Railsのセットアップ

じゃあ、実際にセットアップへ。

…といきたかったけど、セットアップする前に何を作るか決めないと。

ブログやら色々他の人がやってるけど。

せっかくなので、最近マイブームのお小遣い帳のネタで。

お小遣い帳管理サイトをつくろうと思います。

次回から頑張ろう。

（ちゃんと続けられるように…）
