ruby-on-rails - gem 安装ruby-audio-1.6.1错误(使用Mac OS 10.9/Homebrew)

Question

我尝试了其他技巧，但没有用。 (请参见下面的链接)
例如
Gem installation ruby-audio failing
ruby-audio 1.6.1 install error (with installed Libsndfile 1.0.25)

我希望对此有一些反馈。

您可能需要将libsndfile作为通用库安装-默认情况下，它不编译32位片，这是与系统ruby兼容所必需的。

brew uninstall libsndfile
brew install libsndfile --universal
sudo gem install ruby-audio
