Question

我正在运行Mac OSX 10.9.4，rails 4

我正在尝试将Postgresql添加到rails应用程序以部署到heroku。但是，我似乎无法捆绑安装它。当我尝试时：

rails new myapp -d postgresql

这也行不通。我不断收到以下错误消息：

Gem :: Ext :: BuildError：错误：无法构建gem原生扩展。

    /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby extconf.rb

No pg_config... trying anyway. If building fails, please try again with

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:
