我在rails上使用ruby来运行一些OCR任务。我试图使用tesseract-ocr gem（https://github.com/meh/ruby-tesseract-ocr）。
在我的Gemfile中，如果tesseract-ocr gem列出如下：
gem 'tesseract-ocr'
我收到以下错误：
C:\Users\Redacted\Desktop\Rails\cx-master>rails c
The system cannot find the path specified.

（如果我删除了宝石，那么应用就可以了。）
安装了Tesseract：

宝石也是如此：

路径也设定：

问题的症结在于：虽然gesfile中列出了tesseract-ocr gem，但我无法运行该应用程序。我在第3天绕着这个错误绕圈而来，所以一双新鲜的眼睛＆amp;非常感谢任何帮助。
