无法运行这个开源项目http://railsapps.github.com/tutorial-rails-bootstrap-devise-cancan.html。我使用的是 Ruby version1.9.3p286 和 Rails 3.2.8。我已经成功安装了所有 gem，但是当尝试从 RubyMine 运行时，输出如下：

它找不到diff-lcs-1.1.3gem，尝试运行 bundle install 或手动安装 gem。

编辑：看到你的 gem 文件，它不见了

gem "diff-lcs", "1.1.3"

@Baboon 解决方案的一点补充，尝试删除 Gem.lock 文件并bundle install再次运行

但是，一旦您对示例感到满意，您可能会对“rails composer”感兴趣以生成您的 rails 骨架
