Psycopg2 fails to install on python 3 with pip issuing a fatal error

Question

$ yum install python3 postgresql python-devel libpqxx-devel
Loaded plugins: langpacks, refresh-packagekit
Package python3-3.3.2-8.fc20.x86_64 already installed and latest version
Package postgresql-9.3.2-2.fc20.x86_64 already installed and latest version
Package python-devel-2.7.5-9.fc20.x86_64 already installed and latest version
Package 1:libpqxx-devel-3.2-0.5.fc20.x86_64 already installed and latest version
Nothing to do

I am trying to install psycopg2 in my virtualenv to connect django with the postgresql database.

In Fedora 19 and postgresql-9.2 the path to pg_config was:

/usr/pgsql-9.2/bin

In Fedora 20, this directory does not exist.

However pg_config can be found in /usr/bin/pg_config.

Trying to install psycopg2:

 $ export PATH=$PATH:/usr/bin; pip install psycopg2
Downloading/unpacking psycopg2
  Downloading psycopg2-2.5.2.tar.gz (685kB): 685kB downloaded
  Running setup.py egg_info for package psycopg2

... -compiling output here- ...

I would appreciate your help.

Answer 1

You are missing python3 include files

./psycopg/psycopg.h:30:20: fatal error: Python.h: No such file or directory

you can probably find them in the python3-devel package.
