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

Solution 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

Solution 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

Solution 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

Solution 4

On a fresh ubuntu 14.04.2 LTS on an EC2 instance, I was able to install psycopg2 after instaling the following packages:

sudo apt-get install gcc
sudo apt-get install postgres-xc-server-dev
sudo apt-get install libpq-dev
sudo apt-get install postgresql-client-common
sudo apt-get install postgresql-common

And on a fresh AMI linux (CentOS) instance:

sudo yum install postgresql-devel
sudo yum install gcc*

Hope it helps,

i had this problem but was solved by running:

pip install -Iv psycopg2==2.7.7

There is a problem installing the latest version + python3.7
