tesseract-ocr gem 安装正确（包括依赖项）。但是，在启动 rails 服务器时，出现以下编译错误。在这个阶段我从来没有收到过编译错误，所以我会很感激任何帮助。

据我所知，您使用 mac os ...解决任何安装错误的最简单方法是全新安装 :)tesseract和gem 'tesseract-ocr'

如果您安装了自制软件，这很容易

$ brew install tesseract

这将需要一些时间，并将安装 tesseract 本身和所有必要的库

之后，当然

$ gem install 'tesseract-ocr'

（或者$ bundle install如果您将其添加到 Gemfile）
