Ruby on Rails tesseract-ocr gem path错误

我在rails上使用ruby来运行一些OCR任务 . 我正在尝试使用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：

（如果我删除了宝石，但是应用程序工作得很好）

Tesseract已安装：
C:\Users\Redacted\Desktop\Rails\cx-master>tesseract -v tesseract 3.05.01 leptonica-1.74.1 libgif 4.1.6(?) : libjpeg 8d (libjpeg-turbo 1.5.0) : libpng 1.6.20 : libtiff 4.0.6 : zlib 1.2.8 : libwebp 0.4.3 : libopenjp2 2.1.0

宝石也是如此：
C:\Users\Redacted\Desktop\Rails\cx-master>gem list tesseract-ocr *** LOCAL GEMS *** tesseract-ocr (0.1.8)

PATHS也设置：
Path=C:\Program Files (x86)\Tesseract-OCR
TESSDATA_PREFIX=C:\Program Files (x86)\Tesseract-OCR

所以问题的症结在于：当Gesefile中列出了tesseract-ocr gem时，我无法运行该应用程序 . 我正在第3天围绕这个错误转圈，所以一双新眼睛和任何帮助都非常感激 .
