推荐答案

你需要安装 PostgreSQL 的开发包，例如在 Ubuntu 下是 sudo apt-get install libpq-dev... 对于 CentOS，它是 yum install postgresql-devel

You'll need to install the development package for PostgreSQL, which for instance under Ubuntu is a sudo apt-get install libpq-dev... and for CentOS it's yum install postgresql-devel
