我是否仍然可以使用pdf摘录?Heroku不允许在生产中使用sqlite 非常感谢您的帮助 编辑: 对于那些在将来遇到这个问题的人:我试图破解gem,让它与postgres一起工作——这似乎是可行的,尽管它导致gem的性能下降。最终,我创建了一个完全独立的只使用api的应用程序,使用Elastic Beanstalk直接部署到AWS,而不是通过Heroku,这样应用程序就可以使用sqlite3,并调用api应用程序在我的原始应用程序中实现gem功能
这种方法很可能适用于在现有Rails应用程序中导致依赖性问题的任何GEM。我将为您节省时间和麻烦,并查看其他库。有一个PDF文本提取的gem,叫做Heroku 如果无法安装依赖项,则无法使用具有该依赖项的gem。你的选择是
- 使用不同的PDF格式
- 使用Heroku的替代品
- 找到一种方法,在不使用任何gems的情况下实现您自己从Pdf提取所需的功能
- 浏览gem的代码,看看它在哪里使用sqlite,并尝试在不破坏gem的情况下删除该代码

是如何使用SQLite的。问题是HyPDF没有完成我需要它做的事情。当我在ruby脚本中测试Pdf extract时,它做得非常完美。是否要从ruby gem中删除依赖项,或者用pg替换sqlite作为依赖项?我想从一个PDF文档中提取引用(例如,PDF extract extract--references--titles myfile.PDF)。@NoahFinberg如果你必须使用这个gem,那么你就不能部署到Heroku。破解gem以使用Postgres而不是SQLite可能比找到Heroku的替代品要困难得多。
