从 Rails 4.1 升级到 4.2 ffi/rb-inotify 问题

Question

正在将我的 Rails 4.1 应用程序迁移到 Rails 4.2。最后通过将 rb-inotify 固定到版本 0.9.1 来构建它（0.10.1 不构建，需要 Ruby >= 2.2；实际上从 0.9.1 到 0.9.10 的任何版本都给出相同的结果，但是0.9.1 是与 4.1) 一起加载的版本。当我运行 "rails c" 我得到：

Answer 1

这是因为我正在使用最新版本的 SASS。当我将 Gemfile 更改为将 sass 和 sass-rails 固定到旧版本时，这个问题就消失了。很难找到依赖项，但我使用中的 DependencyTree 找到了它。
