【问题描述】：

我正在尝试在 centos 7 上配置 Django 根据这篇文章Here

我安装了

sudo yum install python-pip python-devel postgresql-server postgresql-devel postgresql-contrib gcc nginx

像创建数据库一样为 Django 设置 PostgreSQL 后，... 我尝试在 virtualenv 上安装 psycopg2

pip install django gunicorn psycopg2

但我得到了这个错误，谁能帮帮我？

【解决方案1】：

用 Python 3 测试：

sudo yum groupinstall "Development Tools"
sudo yum install python3-devel
sudo yum install postgresql-libs
sudo yum install postgresql-devel
[sudo] pip install psycopg2

【解决方案2】：

你好像少了一个

sudo yum install postgresql-libs

【讨论】：

【解决方案3】：

http://mirror.centos.org/centos/7/os/x86_64/Packages/

测试一下

yum 安装 python-psycopg2

【讨论】：

【解决方案4】：

postgresql-libs 的安装没有帮助，它实际上需要一个有效的 postgresql 客户端。因此，为 CentOS 7 安装开发包可以解决它（如果这对你来说不是矫枉过正的话）。

yum install postgresql-devel

这开始发生是因为 pip 包停止与 postgresql 客户端二进制文件一起提供，这是有道理的，因为您可能希望在某些情况下使用不同的版本。
