我刚刚切换到 jRuby，并且能够安装我的 gem，但是当我尝试运行 rake 命令时，出现以下错误。如何告诉 jRuby 使用 nokogiri-1.6.0-java 而不是 nokogiri-1.6.0-x86-mingw32？

错误：

它应该可以工作-我对Windows上的Ruby-ing不太熟悉，但这绝对是在PATH上同时拥有MRI和JRuby的问题-最重要的是互相弄乱了GEM_HOME / GEM_PATH（您可以检查从irb by running Gem.path) - 你需要隔离那些 - 确保它们指向正确的方向。

使用 JRuby 时不应加载此类内容： C:/Software/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb

也许总是使用bundle exec可能也会有所帮助，尽管我不确定它是否验证了错误GEM_HOME的后果

这就是为什么没有看到正确的 nokogiri 宝石的原因，因为它正在寻找错误的宝石，因为来自 MRI 的 custom_require.rb
