Install psycopg2 on Ubuntu
Question:
I’m trying to get the python postgres client module installed on Ubuntu 12.04. The guidance is to do the following:
apt-get install python-psycopg2
However, apt says that the package can’t be located.
I’m keen to install this through apt. Is this part of another package that I can install?
Answers:
Using Ubuntu 12.04 it appears to work fine for me:
jon@minerva:~$ sudo apt-get install python-psycopg2

What error are you getting exactly? – double check you’ve spelt psycopg right – that’s quite often a gotcha… and it never hurts to run an apt-get update to make sure your repo. is up to date.
This works for me in Ubuntu 12.04 and 15.10
if pip not installed:
sudo apt-get install python-pip
and then:
sudo apt-get update
sudo apt-get install libpq-dev python-dev
sudo pip install psycopg2
I prefer using pip in case you are using virtualenv:
apt install libpython2.7 libpython2.7-devpip install psycopg2
I updated my requirements.txt to have
psycopg2==2.7.4 --no-binary=psycopg2
So that it build binaries on source
Use
sudo apt-get install python3-psycopg2
for Python3 )
This worked for me:
pip install psycopg2-binary
According to the official documentation https://www.psycopg.org/install/
sudo apt install python3-dev libpq-dev
pip install psycopg2
You should install the library using pip, but this requires multiple system dependencies:
sudo apt-get install libpq-dev python3-dev
Then you can run
pip install psycopg2
Debugging
If you are missing libpq-dev, you will get the error:
Error: pg_config executable not found.
If you are missing python3-dev, you will get the error:
fatal error: Python.h: No such file or directory
sudo apt-get install libpq-dev python-dev
followed by-
pip install psycopg2
