找不到 pg_config 可执行文件 [英] pg_config executable not found

问题描述

我在安装 psycopg2 时遇到问题.当我尝试 pip install psycopg2 时出现以下错误:

I am having trouble installing psycopg2. I get the following error when I try to pip install psycopg2:

Error: pg_config executable not found.

Please add the directory containing pg_config to the PATH

or specify the full executable path with the option:



    python setup.py build_ext --pg-config /path/to/pg_config build ...



or with the pg_config option in 'setup.cfg'.

----------------------------------------
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build/psycopg2

但问题是pg_config实际上在我的PATH中；它运行没有任何问题:

But the problem is pg_config is actually in my PATH; it runs without any problem:

$ which pg_config
/usr/pgsql-9.1/bin/pg_config

我尝试将 pg_config 路径添加到 setup.cfg 文件并使用我从他们的网站 (http://initd.org/psycopg/) 并且我收到以下错误消息！

I tried adding the pg_config path to the setup.cfg file and building it using the source files I downloaded from their website (http://initd.org/psycopg/) and I get the following error message!

Error: Unable to find 'pg_config' file in '/usr/pgsql-9.1/bin/'

但它确实存在！！！

我对这些错误感到困惑.有人可以帮忙吗?

I am baffled by these errors. Can anyone help please?

顺便说一下，我sudo所有的命令.我也在使用 RHEL 5.5.

By the way, I sudo all the commands. Also I am on RHEL 5.5.
