使用postgresql数据库一直都是在服务器同一台机子上,所以一向都正常,今天在其他服务器上调用,执行pip3 install psycopg2后直接暴下面错误:

按错误提示,登录提示地址 http://initd.org/psycopg/docs/install.html 进行查看
发现原来安装psycopg2需要先安装postgresql服务
Prerequisites The current psycopg2 implementation supports: Python version 2.7 Python 3 versions from 3.4 to 3.8 PostgreSQL server versions from 7.4 to 12 PostgreSQL client library version from 9.1
然后按照要求安装好了ps数据库相关服务
yum install https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm yum install postgresql11 yum install postgresql11-server yum install postgresql11-libs yum install postgresql11-contrib yum install postgresql11-devel
安装完成后执行pip安装,还是出错,重新认真查看官网的安装要求后,发现还需要配置 pg_config 路径(这里有点奇怪,我以前在有的服务器上并没有做这个设置,安装也是正常)
按要求在服务器上执行了下面命令:
export PATH=/usr/pgsql-11/bin/:$PATH
然后再执行pip安装psycopg2
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple/ psycopg2
安装成功
