我想使用 rjb 来调用standford parser。我已经设法为 rjb 安装 gem 并按照 rjb 网站中的建议设置 JAVA_HOME 路径。

     gem install rjb
     Building native extensions.  This could take a while...
     Successfully installed rjb-1.4.3
     1 gem installed
     Installing ri documentation for rjb-1.4.3...

    from <internal:lib/rubygems/custom_require>:29:in `require'

    from /usr/local/bin/irb:12:in `<main>'

有人可以告诉我有什么问题吗？

require 'rubygems'先试试require 'rjb'
