UbuntuでRubyOnRailsインストール手順簡易メモ

2012/08/05

この手順でHello World!は動いたが、
よく見ればrubyのバージョンが1.8.7で入っていた。
手持ちのテキスト推奨の1.9.2にしたいのだが、どうしたものか・・・。

Could not find tilt-1.3.3 in any of the sources
Run `bundle install` to install missing gems.

============
gemspecの書き換え
============
$sudo vi /var/lib/gems/1.8/specifications/tilt-1.3.3.gemspec
$sudo vi /var/lib/gems/1.8/specifications/sass-rails-3.2.5.gemspec
$sudo vi /var/lib/gems/1.8/specifications/jquery-rails-2.0.2.gemspec
$sudo vi /var/lib/gems/1.8/specifications/mail-2.4.4.gemspec
$sudo vi /var/lib/gems/1.8/specifications/sass-rails-3.2.5.gemspec
$sudo vi /var/lib/gems/1.8/specifications/libv8-3.3.10.4-x86-linux.gemspec
各ファイルで、上から10行目くらいに【2011-08-25 00:00:00.000000000Z】という記述がある。
<   s.date = %q{2011-08-25 00:00:00.000000000Z}
これを【2011-08-25】に書き換える。
>   s.date = %q{2011-08-25}
この例では、【2011-08-25】であるが、日付はファイルごとに異なる。
日付は変えずに【 00:00:00.000000000Z】を削除する事。
