java - # 的未定义方法 'gsub'

Question

我在运行脚本时不断收到此错误。我对 Ruby 很陌生，所以请原谅我的傲慢。

我正在使用内置了 JRuby 支持的 Nuix 编写脚本。

这是我的代码；

require 'benchmark'
require 'socket'
require 'rubygems'
require 'java'

java_import org.joda.time.format.DateTimeFormat

    module JSwing
      include_package javax.swing
    end

    def dropdown()

        ar = Array.new

        $current_case.getRootItems().each do set
        ar  set.guid()
        end

        names2 = JSwingJOptionPane.showInputDialog(nil, Please enter the name of the item set to export to Relativity., 
                                                            Choose item set, -1, 
                                                            nil, ar.to_java(Object), ar[0])
        if (names2.nil)
        JSwingJOptionPane.showMessageDialog(nil, No Export Set Selected)
            abort()
            end
        return names2
    end

    def writeLine (filepath, line)
        File.open(filepath, 'a') { f1 f1.puts line }
    end 

    def writeLines(filepath, lines)

        #lines.each do output

    bench.report(Write Lines n){
        #writeLinesUTF($path, sharedarray)
    }
    #frame.dispose

}







#end
end

return

这是不断抛出的异常；

undefined method `gsub' for #<#<Class:0x45716032>:0x13685969>
["<script>:194:in `(root)'", "org/jruby/ext/thread/Mutex.java:149:in `synchronize'", "<script>:142:in `(root)'"]

我相信它可能是在 checknull 函数上抛出的，但我不能确定。

感谢任何帮助。

谢谢

在字符串上使用“gsub”之前，如果它不是字符串，请尝试在此之前使用“to_s”将其转换为字符串。像这样:

something.to_s.gsub(...)
