Синтаксическая ошибка тега скрипта Rails?

Запуск моего приложения Rails на новом хосте и был обновлен до версии Ruby v2.0.0 с версии 1.9.3, и я получаю эту странную синтаксическую ошибку. Это выглядит так:

Completed 500 Internal Server Error in 178ms

Я не уверен, что случилось с тегами <script>, поэтому я вставлю файл (_contents.html.erb) здесь:

Сейчас эти Javascripts находятся в нижней части моего файла _contents.html.erb.
