安裝simplecov後JRuby rspec異常

嘗試添加simplecov到我的Rails應用程序（Jruby 1.6.4，Ruby 1.9.2，Windows）。我說「simplecov」到Gemfile中，捆綁安裝，下面我spec_helper的頂部：安裝simplecov後JRuby rspec異常

require 'rubygems' 
require 'simplecov' 
SimpleCov.start 'rails'

運行時我得到以下異常：

$ bundle exec rspec --debug spec

不認爲你需要require'rubygems';我知道我的spec_helper.rb沒有它。我使用spork雖然所以我的第一行是要求'spork' – 2011-12-29 22:14:01
