ModuleNotFoundError: No module named 'psycopg2'

I'm using Mac os. I installed pyscopg2 successfully (pip3 install psycopg2)

But when I try to import psycopg2 I get the following message:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'psycopg2'

You can install 'psycopg2==2.7.5' using this command:

pip install psycopg2==2.7.5

psycopg2 2.7.5 is the last version that doesn't require building from source. Although it'll throw the following warning every time it is initialized in code: 

UserWarning: The psycopg2 wheel package will be renamed from release 2.8; in order to keep installing from binary please use "pip install psycopg2-binary" instead. For details see: <http://initd.org/psycopg/docs/install.html#binary-install-from-pypi>.

So you can alternatively use pip install psycopg2-binary

First Install psycopg2 on both the python version, only if you don't which one you are targetting.

Command - pip install psycopg2 (for python 3) Command - pip3 install psycopg2 (for python 2)

Although, if it does not work there is one more way as well using the .whl(wheel file)

using the wheel - pip install and from here you can download .whl file 

pip install your.whl

Download the wheel file taking the version of your python in mind.

Psycopg2 whl file

Hope it helps.
