简要背景：
我的 Gemfile 看起来像这样：
source 'https://rubygems.org'
gem 'rails', '3.2.3'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
group :development do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.9.0'
end
gem 'therubyracer'
# group :production do
# gem 'pg', '0.12.2'
# end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.4'
gem 'coffee-rails', '3.2.2'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platform => :ruby
gem 'uglifier', '1.2.3'
end
group :test do
# gem 'capybara', '1.1.2'
end
gem 'jquery-rails', '2.0.0'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'
在我的应用程序文件夹中运行 bundle install 时，我收到以下错误：
$ bundle install

An error occured while installing diff-lcs (1.1.3), and Bundler cannot continue.
Make sure that `gem install diff-lcs -v '1.1.3'` succeeds before bundling.
但是，如果我注释掉gem rspec-rails', '2.9.0'，它的安装很顺利。我认为问题在于 gem 的安装方式。请帮忙看看怎么办？如果您需要更多信息，请告诉我。
