所以，就像一个优秀的程序员一样，我正准备申请即将过渡到Cedar-14。
程序在Cedar 10上工作正常。对Cedar 14无效，RJB存在某种问题。当我尝试推送应用程序时，我得到的错误是：

与pg或'rjb`相关。
在雪松10版本上，我已将rjb锁定到v1.4.9。然而，这对雪松14造成了同样的问题，并将其升级到v1.5.3没有帮助。
如果我完全删除rjb宝石，那么该应用程序的开发工作完全正常，但在上传到Heroku时会完全中断（“您的应用程序出错，请在几分钟内重试”屏幕死亡）。
我看过this similar question，但是heroku似乎已经删除了建议解决方案中添加的“实验室”。我也在我的Gemfile中弄乱了ENV ['JAVA_HOME']而没有结果。
我没有想法，我甚至找不到任何有关如何检查Heroku上的mkmf.log文件的信息，以获取任何额外的线索。
gem install rjb -v '1.5.3'可以自行运行，但在我尝试推送整个应用程序时不会改变任何内容。
如何检查Heroku上的mkmf.log文件？
我可以尝试使用rjb的替代方案（显然Heroku认为它需要它用于某些东西，可能是用PDF生成PDF）？我已经阅读了一些关于Jruby的内容，但显然其中很多其他宝石都不受支持，因此我的应用程序的其余部分可能无效。
是否还有一些其他明显或现有的解决方案我缺席了？
这是我的Gemfile：

# This directory changed from Heroku "cedar" stack to "cedar 14" stack
