当我尝试创建一个 rails 应用程序“rails new project”时，我得到以下信息：
/usr/local/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:298:in `to_specs': Could not find 'atomic' (>= 0) - did find: [atomic-1.1.13-java] (Gem::LoadError)

我在这里讨论了上一个问题ubuntu 12.04 ruby 2.0 rails: Could not find 'thread_safe'。
安装线程安全 gem 后，错误消失了，然后Could not find 'atomic' error.我尝试了：
gem install atomic
有各种版本，但我仍然收到此错误。我注意到今天其他用户也出现了这些问题。
