Question

今天开始我们的Heroku部署。

   Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

最近添加的宝石包括ffi：

  gem 'sass', github: 'nex3/sass'
  gem 'sass-rails'
  gem "compass", "~> 1.0.0.alpha.18"
  gem "compass-rails", "~> 1.1.2"
  gem 'susy', github: 'ericam/susy', branch: 'susy-next'

有没有人向Heroku发送ffi以避免这种情况？

Answer 1

我按照以下步骤处理同样的问题。我建议做同样的事情

将ffi添加到本地gemfile，将其版本指定为1.9.0，例如gem 'ffi', '= 1.9.0'
从本地方框gem uninstall ffi -v 1.9.3
运行bundle update ffi
提交更改
将更改推送到heroku。

如何在Heroku上安装ffi
