The best answers to the question “pg_config executable not found” in the category Dev.
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.
On Mac OS X, I solved it using the homebrew package manager
brew install postgresql
pg_config is in
libpq-dev in Debian/Ubuntu,
libpq-devel on Centos/Fedora/Cygwin/Babun.)
Also on OSX. Installed Postgress.app from http://postgresapp.com/ but had the same issue.
pg_config in that app’s contents and added the dir to
It was at
/Applications/Postgres.app/Contents/Versions/latest/bin. So this worked:
Have you installed
If you already have, try also installing
sudo apt-get install libpq-dev python-dev
