宝石安装ruby-audio失败

Question

我克隆了一个现有的存储库,现在正在运行bundle install- 由于某种原因,它在ruby-audio gem失败了.

Installing ruby-audio (1.6.1) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of

  Try passing --with-sndfile-dir or --with-sndfile-lib and --with-sndfile-include
  options to extconf. If there are spaces in the path on windows, it may not work.

Gem files will remain installed in /Users/thisuser/.bundler/tmp/5253/gems/ruby-audio-1.6.1 for inspection.
Results logged to /Users/thisuser/.bundler/tmp/5253/gems/ruby-audio-1.6.1/ext/rubyaudio_ext/gem_make.out
An error occured while installing ruby-audio (1.6.1), and Bundler cannot continue.
Make sure that `gem install ruby-audio -v '1.6.1'` succeeds before bundling.

老实说,我不知道该怎么做.谷歌搜索显示与mysql gem相同的错误,解决方案是mysql特定的.

有没有人偶然发现这个？如果没有,有没有办法明确告诉rails忽略那个gem？从gem文件中删除它并bundle install再次运行并没有成功.

谢谢你的帮助!

运行后brew install libsndfile我得到以下输出:

我尝试了所有建议的命令 - 无济于事.我还能做些什么来解决这个问题？

所以,我们让它一起工作,我想我会分享我必须采取的步骤来完成这项工作.感谢所有评论的人!

1. 问题是,在安装gem时,它无法找到 libsndfile
2. 要安装它,我必须运行brew install libsndfile(如果你还没有安装自制软件),这不起作用,所以我不得不......
3. ...将Xcode更新到最新版本并安装Xcodes命令行工具(不要问我为什么,但我不得不这样做.)
4. 然后我跑了brew install libsndfile,哪个有效
5. 最后但并非最不重要的是我又跑bundle install了,最后安装了所需的宝石.
