The tesseract-ocr gem installed correctly (including dependencies). However when launching the rails server I get the following compile error. I have never received a compile error at this stage, so I would be grateful for any help.
tesseract-ocr gem正确安装（包括依赖项）。但是，在启动rails服务器时，我收到以下编译错误。我在这个阶段从未收到编译错误，所以我将不胜感激任何帮助。

as far as i can see you use mac os... simplest way to solve any installation mistakes is clean install :) of tesseract and gem 'tesseract-ocr'
据我所知，你使用mac os ...解决任何安装错误的最简单方法是清洁安装:) tesseract和gem'tesseract-ocr'
it is pretty easy if you have homebrew installed
如果你安装了自制软件，这很容易
$ brew install tesseract
it will take some time and will install tesseract itself and all necessary libs
这需要一些时间，并将安装tesseract本身和所有必要的库
and after, of course
当然，之后
$ gem install 'tesseract-ocr'
(or $ bundle install if you added it to Gemfile)
（如果你将它添加到Gemfile，则为$ bundle install）
