config executable not found
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
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
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/'
But it is actually THERE!!!
I am baffled by these errors. Can anyone help please?
By the way, I sudo all the commands. Also I am on RHEL 5.5.
pg_config位于postgresql-devel （Debian / Ubuntu中的libpq-dev ，Cygwin / Babun上的libpq-devel ）。
在Mac OS X上，我使用自制软件包管理器解决了这个问题
brew install postgresql
Have you installed python-dev? If you already have, try also installing libpq-dev
sudo apt-get install libpq-dev python-dev
