Rails プロジェクトの初期化

Ubuntu 12.04 上にとりあえず簡単な Rails プロジェクトを作成した。
このあたりの作業は毎回ほぼ同じになるのでログとして残しておこう。

# デフォルト設定の確認
$ cat ~/.railsrc
-T -d postgresql --skip-bundle
$ mkdir projects/new_prj
$ cd projects/new_prj
$ bundle init
$ echo "gem 'rails', '3.2.3'" >> Gemfile
$ bundle install --path vendor/bundle

Post-install message from rdoc:
Depending on your version of ruby, you may need to install ruby rdoc/ri data:

<= 1.8.6 : unsupported
 = 1.8.7 : gem install rdoc-data; rdoc-data --install
 = 1.9.1 : gem install rdoc-data; rdoc-data --install
>= 1.9.2 : nothing to do! Yay!
