Ruby on rails ruby web抓取工具scrubyt错误：-kernel_require.rb:112:in`require'；：无法加载这样的文件--jcode（LoadError）

我也在使用scrubyt web scraping运行一个web scraping脚本。当我运行那个脚本时，我得到上面的错误。 以下是完整的跟踪：-

我将感谢任何帮助。非常感谢。

尝试从

scrubyt.rb

file.scrubyt中删除行

require'jcode'

？从没听说过。我的建议？摆脱它。我尝试过它后，删除，但仍然是相同的问题。你能告诉我任何基于ruby的网页抓取工具可以抓取JavaScript和基于ajax的网页吗？我使用的是Mechanize，但它不能废弃基于JS和ajax的页面。任何建议都将不胜感激。非常感谢。
