Railsで優れたスプレッドシートを処理できるようにしたいと思います。
だから私はspreadsheetライブラリを使用しています。
ただし、rubygemsを使用してスプレッドシートをインストールすると、例外が発生します。

次に、doSomethingControllerで、次のコードを記述しました。

require 'spreadsheet'

しかし、サーバーはエラーを返します

cannot load such file -- spreadsheet

何が起こったのか、どうすれば例外を修正できるのかを理解するのを手伝ってくれませんか

私の環境：

ruby 1.9.3
rubygem 1.8.16

gem list | grep spreadsheet
