我完全坚持这个错误.使用Rails 3.1试图实现Formastic Bootstrap gem并获得错误:

`':没有这样的文件要加载 - formtastic/helpers/buttons_helper(LoadError)

formastic.rb

Formtastic::Helpers::FormHelper.builder = FormtasticBootstrap::FormBuilder

gem 'formtastic'

gem 'formtastic-bootstrap'

buttons_helper

module FormtasticBootstrap
  module Helpers

        html_options[:class] ||= "actions"

        if html_options.has_key?(:name)
          ActiveSupport::Deprecation.warn('The :name option is not supported')

        if block_given?
          template.content_tag(:div, html_options) do
            yield
          end          
        else
          args = [:commit] …
