ImportError: No module named 'psycopg2'

I've already installed the dependencies with sudo apt-get build-dep python-psycopg2 and then installing psycopg2 with sudo pip install psycopg2 and even with easy_install psycopg2. But even after all this, if I run python3 code.py I get 

ImportError: No module named 'psycopg2'

If I run sudo apt-get build-dep python3-psycopg2 I get

Picking 'psycopg2' as source package instead of 'python3-psycopg2'

0 upgraded, 0 newly installed, 0 to remove and 144 not upgraded.

Same with sudo apt-get build-dep python-psycopg2

Please help.

In my case, pip3 install psycopg2 made psycopg3 available for python3, while I was trying to execute my code in python 2.7 by default

so changing my call from

python foo.py to python3 foo.py helped

I faced the same issue. I tried 'sudo apt-get build-dep python-psycopg2' It didn't work. I was trying to connect to a postgres database. It turns out that I didn't have postgresql installed. Once I installed it, the error went away.

If you are using the Anaconda distribution, make sure to go with: conda install -c anaconda psycopg2=2.6.2

its always better to work in virtualenv and not mess up with your system

try:

virtualenv -p /usr/bin/python3 test_env
source test_env/bin/activate
pip install psycopg2

run python and try to import
if you insist on installing it on your systems python try:

pip3 install psycopg2
