Trouble installing psycopg2 on CentOS
提问by hdx
I'm trying to install psycopg2 on CentOS, I followed everything on this tutorialfrom "On with it: Installing Python 2.6" all the way to when it imports psycopg2, but when I try to import I get the following error:
我正在尝试在 CentOS 上安装 psycopg2，我按照本教程中的所有内容从“使用它：安装 Python 2.6”一直到导入 psycopg2，但是当我尝试导入时出现以下错误：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/python2.6/lib/python2.6/site-packages/psycopg2/__init__.py", line 69, in <module>
from _psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID
ImportError: libpq.so.5: cannot open shared object file: No such file or directory
How to troubleshoot this?

psycopg2 is a python wrapper around the PostgreSQL libraries, so you need those installed on your system too.
psycopg2 是围绕 PostgreSQL 库的 Python 包装器，因此您也需要在系统上安装这些库。
Since you're using CentOS, try this from the command line to install the postgre libs.
由于您使用的是 CentOS，请尝试从命令行安装 postgre 库。
yum install postgresql-libs
yum install postgresql-libs

- Forget your tutorial.
- Install EPEL
- yum install python-psycopg2
- 忘记你的教程。
- 安装 EPEL
- yum 安装 python-psycopg2
Django supports Python 2.4just fine. If you really need Python 2.6 you can also use EPEL (yum install python26) - but there's no psycopg2 package for it yet.
Django支持 Python 2.4就好了。如果你真的需要 Python 2.6 你也可以使用 EPEL ( yum install python26) - 但还没有 psycopg2 包。

I followed the first answer to install python libs:
我按照第一个答案安装python库：
yum install postgresql-lib
but it didn't work, so I also did a yum install of the devel and python:
但它没有用，所以我还对 devel 和 python 进行了 yum 安装：
yum install postgresql91-devel.x86_64
yum install postgresql91-python.x86_64
Not sure which one did it, but my guess is the devel.
不知道是哪一个做的，但我的猜测是开发。
