Deploy OCR for Heroku Rails Application

Question

I need the OCR feature for a Rails application on Heroku. My attempts to get tesseract to work were not successful. Anyone have any suggestions? It's hard to believe that something that is core like OCR is not supported by some ubiquitous one like Rails on Heroku.

BACKGROUND FOR EFFECTIVELY OBTAINING TESSERACT FOR WORK

• The app works fine on MacOS using tesseract and gemes tesseract-ocr binaries
• Heroku does not have tesseract built-in support and does not support the installation of binary files (see Setting Security Paths in Heroku ).
• Most questions about tesseract on Heroku are unanswered ( Using Tesseract on Heroku with Django , Tesseract-OCR on Heroku with Node.js )
• Unable to get tesseract_bin gem to download locally (not tried on Heroku)
• The route of using buildpack-libraries seems overwhelming to me (and if this approach is viable, I don’t understand why someone hasn’t provided a pre-packaged solution).
