Question

我试图在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

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

pip install django gunicorn psycopg2

但是我收到了这个错误，有人可以帮帮我吗？

Answer 1

你似乎错过了

sudo yum install postgresql-libs

Answer 2

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

测试此

yum install python-psycopg2

Answer 3

postgresql-libs的安装无济于事，它实际上需要有效的postgresql客户端。因此，为CentOS 7安装devel软件包即可解决该问题（如果您认为这不是一个过大的选择）。

yum install postgresql-devel

这是由于pip软件包停止了与postgresql客户端二进制文件一起发货而开始发生的，这很有意义，因为在某些情况下您可能想使用其他版本。

Answer 4

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

python - 无法在centos 7上安装psycopg2
