当我开始运行我的 Rails 服务器时，当我转到 localhost:3000 时，我收到此文件未找到错误。我收到的信息是couldn't find file 'jquery.effects.core'。从我的 repo 中提取应用程序的新克隆到重新安装 Rails 和 Ruby，我几乎已经做了所有我能做的事情，但这一切都导致了同样的错误。有任何想法吗？

当我运行我的 rails 服务器时，我得到以下输出：

sudo rails s
=> Booting Thin
=> Rails 3.2.9 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

这是我的 Gemfile

source 'https://rubygems.org'

gem 'rails', '3.2.9'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'pg'
gem 'rails_admin'
gem 'devise'
gem 'cancan'
gem 'simple_form'
gem 'kaminari'
gem 'bootstrap-kaminari-views'
gem 'recaptcha', :require => 'recaptcha/rails'
gem 'acts_as_commentable_with_threading'

# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
end

group :production do
  gem 'thin'
end

gem 'libv8', '~> 3.11.8'
gem "therubyracer", '>= 0.11.0beta8', :require => 'v8'
gem 'twitter-bootstrap-rails', :git => 'git://github.com/seyhunak/twitter-bootstrap-rails.git'
gem "less-rails"

gem 'paperclip'
gem 'aws-sdk'

gem 'jquery-rails'

编辑（已解决）：这是我的 application.js 文件。当我取消注释该行时，一切似乎都有效= require jquery。我不知道如何解释这一点，因为即使该行已被注释掉，也有其他人在使用同一组源代码时不会遇到此问题。

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.

//= require jquery <----------------

看起来这是 RailsAdmin gem 中的一个错误：

运行“捆绑更新”为我解决了这个问题。
