何を作るか
今回気持ちを新たにrailsアプリケーションを作ってみる。。が！
何を作ろうかと思っていましたら、ちょうど昔作った「家計簿アプリ」を
スマホでも見たいという話もあって、WEBアプリケーションとして作成しようと
決めました。
まずは、、
環境が若干古いので、全てアップデート。
【現在の環境】
Mac Book Air
$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin12.2.0]
$ rails -v
Rails 3.0.17
古いなあorz。でも前のバージョンを使ってなんやかんやする時もあるかもしれないので、
色んなRubyのバージョンを管理してくれる、RVMを使用する。
上記サイトを参考に、RVMをインストール。
$ git clone --depth 1 git://github.com/wayneeseguin/rvm.git

うまくインストールされたっぽい。
次にruby 2.0.0をインストール。
$ rvm install 2.0.0

ruby 2.0.0がインストールされました。
次にrailsのインストールですが、rvmにはrailsの環境を整えるのに便利なgemsetというのが
あるらしいです。
新しいruby 2.0.0のgem環境なので、上記サイトにあるようにあまりgemが入ってないかと
思いきや、なんやかんや入っていました。
$ which ruby
/Users/{ユーザ名}/.rvm/rubies/ruby-2.0.0-p353/bin/ruby
$ gem list
*** LOCAL GEMS ***

rails用に新規のgemsetを作成。
$ rvm gemset list
gemsets for ruby-2.0.0-p353 (found in /Users/{ユーザ名}/.rvm/gems/ruby-2.0.0-p353)
=> (default)
global
$ rvm gemset create rails40

ruby-2.0.0-p353 - #generating rails40 wrappers.
$ rvm gemset list
gemsets for ruby-2.0.0-p353 (found in /Users/{ユーザ名}/.rvm/gems/ruby-2.0.0-p353)

global
rails40
作成した環境へ切り替える。
$ rvm 2.0.0@rails40
$ ruby -v
ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-darwin13.0.0]
$ rvm gemset list
gemsets for ruby-2.0.0-p353 (found in /Users/{ユーザ名}/.rvm/gems/ruby-2.0.0-p353)
(default)
global
=> rails40
この環境のgemにrailsをインストールする。
$ rails -v
Rails 4.0.2
無事railsをインストール。
新規プロジェクト作成し、起動を確認。ん〜なんとかうまくいってる感じ。
