升级到Rails 3.1后图像未找到错误,如何修复？

Question

我从rails 3.0升级到rails 3.1后,每次加载rails服务器时都会收到此警告.不确定它是什么.我已经尝试重新安装从rvm和ruby到我所有宝石的所有东西.我的猜测是rails 3.1中不支持某些gem,但我似乎无法找到哪一个或由于某种原因我没有为特定gem安装依赖项.

这来自libnotify在OSX上使用gem.您可以通过在Gemfile中指定操作系统来避免这种情况,如下所示:

gem 'libnotify' if /linux/ =~ RUBY_PLATFORM
gem 'growl' if /darwin/ =~ RUBY_PLATFORM
