Ruby on rails 用于ruby/rails的OCR tesseract gem-如何安装？

tesseract ocr gem安装正确（包括依赖项）。然而，当启动rails服务器时，我得到了以下编译错误。在此阶段，我从未收到过编译错误，因此，如果有任何帮助，我将不胜感激

据我所知，你使用的是mac os。。。 解决任何安装错误的最简单方法是清洁安装：）的

tesseract

和

gem'tesseract ocr'

如果您已经安装了

$ brew install tesseract

这将需要一些时间，并将安装tesseract本身和所有必要的LIB

当然，之后呢

$ gem install 'tesseract-ocr'

---

（或者，

$bundle install

如果你把它添加到Gemfile中的话）

好吧，你实际上需要看看第一行提到的日志文件：

/var/folders/hm/6n4h3d1s49b\u pxt2m51gr39c000gn/T/.ffi-inline-501/793babd774d7ac74de2eb789882efa735f45b30b.log

@RobertK添加了日志文件。哇，感谢写这篇文章的人。unix-y程序很少实际向您显示日志文件的完整路径，我认为。可能会有帮助（与您的错误相同）：@JacksonHenley我在更新

tesseract

二进制文件时遇到同样的问题。如果您想在gem中使用

tesseract ocr

，有一种方法可以做到这一点，不是每个人都需要在外部安装吗？换句话说：你能把

tesseract ocr

打包成一块宝石吗？我真的不明白你的问题<代码>tesseract ocr已经是gem。如果您想在另一个gem的捆绑包中使用它，您可以在新gem的gemfile中定义它。它要求您

brew安装tesseract

，是否有办法实现这一点。假设我正在制作一个新的宝石：

awesome\u gem

，我想在这个宝石中使用tesseract。但是，我不希望gem的用户也必须安装tesseract。我希望它是简单的：

gem安装awesome\u gem

，然后他们就可以开始使用它，从而使用tesseract。有办法吗？嗯。。。我想是的。您可以在gem中包含任何您想要的内容，比如tesseract和rubyshell脚本的源代码，以便在需要安装到的每个操作系统上本机构建它。但它想在gem=）中编写mini-brew

$ gem install 'tesseract-ocr'
