Install psycopg2 on Ubuntu

问题:

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?

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

Use

sudo apt-get install python3-psycopg2

for Python3 )

I prefer using pip in case you are using virtualenv:

1. apt install libpython2.7 libpython2.7-dev
2. pip install psycopg2

I updated my requirements.txt to have psycopg2==2.7.4 --no-binary=psycopg2 So that it build binaries on source
