我尝试部署我的应用程序的Heroku的捆绑过程中失败，但我收到以下错误：

我们已经遇到了同样的问题：How to install ffi on Heroku

我们跟踪它到指南针试图在Heroku上安装不兼容的可执行文件（FFI），并且它不安装。这很愚蠢，因为我们不需要在Heroku上安装FFI，因为它只是一种开发模式依赖。

罗盘需要捆绑它的依赖关系，而不是在生产服务器上安装不必要的gem/executables（使用add_development_dependency），或者Heroku需要允许它安装在/ tmp目录中。

遗憾的是，我们已经恢复了我们的代码不使用罗盘的测试版，我们还没有解决这个问题，我们正在考虑切换到波旁，不具有不必要的生产依赖。
