我正在尝试使用新的rails应用程序安装pg gem,但我一直收到同样的错误：

Building native extensions.  This could take a while...
ERROR:  Error installing pg:
    ERROR: Failed to build gem native extension.

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.

我已经尝试过这个问题：How to install PostgreSQL’s pg gem on Ubuntu?
但没有什么对我有用.

顺便说一句,这是ruby1.9.2和Rails 3.2.

谢谢

解决方法

安装postgresql 9然后安装你的gem.

sudo apt-get install postgresql libpq-dev

现在,跑

gem install pg

然后

捆绑安装
