Question

My Rails应用程序通过localhost在我的机器上运行良好，但是当我将它部署到Heroku时，我得到了这个错误列表：

除了Heroku可能与我正在使用的Ruby Tesseract gem有些问题之外，我似乎无法做出正面或反面。也许是依赖的问题？

更新：

进一步搜索后，结果是the issue is related to the Tesseract gem。

根据支持票我需要设置这些路径......

ENV['CFLAGS'] = '-I/path/to/the/headers'
ENV['LDFLAGS'] = '-L/path/to/the/libs'

...但我不知道如何设置它们或者在部署到Heroku的Rails应用程序上实际上应该是header / libs的路径。任何见解？

Answer 1

这是Heroku对我与他们一起提出的关于此事的票的回复：

您好，

不幸的是，我们不支持在我们的堆栈中安装额外的库或二进制文件。最好的解决方法是将这些提供给您的项目。您需要使用64位Linux版本才能使它们在Heroku上运行;静态编译还可以帮助确保包含所需的任何依赖项。同样，对于依赖外部库的gem，我们建议静态编译gem并将其存储到项目中。

我们意识到这不是一项微不足道的任务，而且很难开展工作，我们希望将来能够提供一种更简单的方法。不幸的是，当这种改进的功能可用时，我们没有ETA。

如果您希望尝试提供二进制文件，库或gem，则可以使用Heroku作为构建环境。我们的一位工程师创建了一个构建服务器，允许您上传源代码，运行编译步骤，然后下载生成的二进制文件。你可以在这里找到这个项目： https://github.com/heroku/vulcan

谢谢， Heroku支持

换句话说，去其他地方部署。

Answer 2

我也面临同样的问题，希望我们能互相帮助。

我找到了a way to set config var on Heroku。根据meh对github的评论，看起来它需要在Heroku上安装Tesseract。也许你可以问Heroku在哪里安装位置？

我还发现这个other gem成功地融入了Heroku。不幸的是，它仍然使用tesseract 2.04。

在Heroku中配置环境路径
