我正在尝试让docsplit使用我的rails应用程序.现在我只想让它在本地运行.我安装了gem和所有依赖项.所有基本示例都在命令行中工作,我能够得到

Docsplit.extract_pdf('example.doc')

在我的rails应用程序中工作.但是当我尝试使用extract_images时,即

Docsplit.extract_images('example.doc', :size => '1000x', :format => [:png, :jpg])

我收到以下错误:

Docsplit::ExtractionFailed (sh: pdfinfo: command not found):
  docsplit (0.6.1) lib/docsplit/info_extractor.rb:23:in `extract'
  (eval):3:in `extract_length'

  docsplit (0.6.1) lib/docsplit.rb:58:in `extract_images'
  app/controllers/sandbox_controller.rb:53:in `split_doc'

我仔细检查并安装了所有依赖项.我猜我错过了rails中的配置.

谢谢.
