该问题似乎是由中兴创业板和/或其附属机构ffi、spoon造成的。如果我从Gemfile中删除zxing,Heroku会编译应用程序,一切正常。在重新添加gem时,我遇到了同样的问题。我还尝试在application.rb中将config.assets.initialize_on_precompile设置为true和false,但没有效果。我现在有点不知所措,不知该怎么办

我的应用程序位于Cedar stack上,并在开发和生产中使用PostgreSQL


有人能提供任何建议吗?

< P>是的,很不幸,你不能使用C++或java依赖项的任何东西。我很难找到一个纯ruby且工作良好的QR解码器。

这看起来像是编译阶段推送过程中的超时,而不是编译错误。我是《中兴》的作者,实际上不知道什么是“宝石”。我不知道这是什么,但如果有问题,这是与其他人的包装,这与代码本身无关。如果我阅读的东西正确,ZXing宝石需要JRuby工作。。。这是正确的吗?如果是这样的话,我相信它对Heroku不会起作用。与其说是回答,不如说是评论!
