python-can'；t在centos 7上安装psycopg2

我正在尝试在centos 7上配置Django 本文认为,

我安装了

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

在为Django设置PostgreSQL（如创建数据库）之后。。。 我尝试在virtualenv上安装psycopg2

pip install django gunicorn psycopg2

但是我犯了这个错误， 有人能帮我吗

您似乎缺少一个

sudo-yum安装postgresql-libs

测试这个

yum安装python-psycopg2

---

安装

postgresql libs

没有帮助，它实际上需要一个有效的postgresql客户端。因此，安装适用于CentOS 7的devel软件包可以解决这个问题（如果这对您来说不算过分的话）

这是因为pip包停止附带postgresql客户端二进制文件，这很有意义，因为您可能希望在某些情况下使用不同的版本。

使用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

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