我试图制作一个OCR应用程序，然后将gem添加到gemfile＆＃34; tesseract-ocr＆＃34;运行服务器时，它显示以下错误：

我在互联网上搜索了很多，但找不到解决方案。我非常感谢你的帮助。

实际上问题是在mac上安装了tesseract，安装了tesseract-ocr gem已经失去兼容性的当前版本。

The solution in this answer显示了如何安装与当前（截至2016年5月）tesseract gem

兼容的旧版tesseract-ocr 0.1.8 
brew install https://raw.githubusercontent.com/Homebrew/homebrew/8ba134eda537d2cee7daa7ebdd9f728389d9c53e/Library/Formula/tesseract.rb
