Error: command 'gcc' failed with exit status when installing psycopg2

Question

I need to install psycopg2 for openerp installation process, but I always faced that error. I've already used pip and easy_install and my gcc is the latest version. I really need your help to solve my problem.

This is my complete error with easy_install:

[root@server01 ~]# easy_install psycopg2

Answer 1

You'll need to install the development package for PostgreSQL, which for instance under Ubuntu is a sudo apt-get install libpq-dev... and for CentOS it's yum install postgresql-devel

Answer 2

For the case of CentOS, I had this very same problem, that I solved installing these packages:

sudo yum install postgresql-libs
sudo yum install postgresql-devel
sudo yum install python-devel

only then, I was able to perform successfully:

sudo easy_install psycopg2

Answer 3

May Your system is missing the Python headers. To fix this, run:

sudo apt-get install python-dev

or

sudo apt-get install python3-dev
