我正在使用jruby模式1.9。

➜  nittresults git:(master) ✗ ruby -v
jruby 1.6.7.2 (ruby-1.9.2-p312) (2012-05-01 26e08ba) (Java HotSpot(TM) 64-Bit Server VM 1.6.0_24) [darwin-x86_64-java]
➜  nittresults git:(master) ✗ which gem
gem: aliased to jruby --1.9 -S gem
➜  nittresults git:(master) ✗ which irb
irb: aliased to jruby --1.9 -S irb

我创建了一个 gem nittresults，安装后我无法在 irb 中加载它。错误信息如下所示

➜  nittresults git:(master) ✗ gem list | grep -i nitt
nittresults (0.0.1)
➜  nittresults git:(master) ✗ irb
irb(main):001:0> require 'nittresults'
LoadError: no such file to load -- nittresults
    from org/jruby/RubyKernel.java:1042:in `require'
    from /Library/Frameworks/JRuby.framework/Versions/Current/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require'
    from (irb):1:in `evaluate'
    from org/jruby/RubyKernel.java:1088:in `eval'
    from org/jruby/RubyKernel.java:1410:in `loop'
    from org/jruby/RubyKernel.java:1197:in `catch'
    from org/jruby/RubyKernel.java:1197:in `catch'
    from /Library/Frameworks/JRuby.framework/Versions/Current/bin/jirb:13:in `(root)'

我怎样才能让它加载到 irb 内部？我在osx雪豹10.6.8上。

这是输出 oggem env

您需要先激活 ruby​​gems：

require 'rubygems'
gem 'nittresults'
require 'nittresults'
