Ruby Wagrant with Chef-配置VM时出错

我有一个困难的时间得到一个虚拟机设置与流浪汉

每当我使用vagrant>provision时，Chef都会失败：

[2014-03-15T19:16:08+00:00]错误：chef_gem[pg]（postgresql:：ruby第39行）出现错误：gem:：Installer:：ExtensionBuildError:错误：无法生成gem本机扩展

我很难理解在这里该做什么。我已经在虚拟机上手动安装了postgres，从cheffile中删除了postgres，但是Chef仍然失败

感谢您的帮助。

您需要在虚拟机上为pg gem安装postgres客户端库

您需要包括安装扩展的方法
