ox -v 2.0.11 Gem :: Installer :: ExtensionBuildError：错误：无法构建gem本机扩展

Question

Mac OSX Mountain Lion，Rails 4.0.0，Ruby 1.9.3，Postgresql

我正在与一个朋友一起从事一个项目，当我克隆到他的主代码（使用“ git clone”）并尝试运行“捆绑安装”时，收到以下消息：

    An error occurred while installing ox (2.0.11), and Bundler cannot continue.
    Make sure that `gem install ox -v '2.0.11'` succeeds before bundling.

在本地安装Postgresql并按照类似的StackOverflow问题中的建议创建新路径后，我收到了完全相同的错误消息：

    PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH"

我也尝试过手动安装gem“ gem install ox -v 2.0.11”，但是也以相同的消息结尾。

关于为什么发生这种情况有什么想法吗？

谢谢！

问题解决了！ 谢谢皮蓬！

我使用rvm安装了不同版本的ruby －如果您没有它，这里是指向站点https://rvm.io/的链接，或者可以在终端中使用以下命令进行下载：“ $ \\ curl -L https://get.rvm.io | bash”

以下是我用于加载新的ruby版本的命令：

    rvm get head
    brew install autoconf automake
    rvm reload
    rvm use ruby-1.9.3-p327-fast --default

然后重新运行“捆绑安装”。
