I can not install pg_config as an executable

Answer 1

You need to install the postgresql-devel .

Or create Postgres from the source code, and then you will have pg_config not from the package.

Answer 2

For AWS linux (or RedHat, for that matter) use:

 sudo yum install postgresql-devel 

Answer 3

The above answer is correct: you need to install the -devel package. In addition, I found through this comment that you may need to manually specify where to look for pg_config to build psycopg2 .

In particular, I finished work

 python2.7 setup.py build_ext --pg-config /usr/pgsql-9.3/bin/pg_config install 

Note that this path will depend on your version of postgres.
