rake db:migrate失敗

では早速、テーブルを作ってみる。

railsのmigrate機能を使ってみたいので、modelをgenerate

H:\Rails\hondana>ruby script/generate model Books
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/books.rb
      create  test/unit/books_test.rb
      create  test/fixtures/books.yml
      create  db/migrate
      create  db/migrate/001_create_books.rb

適当にcreate_books.rbを変更して、rake

H:\Rails\hondana>rake db:migrate
C:/Program Files/ruby-1.8/bin/rake:17:
 undefined method `require_gem' for main:Object
 (NoMethodError)

あふん・・・
