I'm trying to install Odoo 13 on Ubuntu 20.04, I have followed different procedures to install it like this one for example, but I always got this psycopg2 error (below this paragraph) when I reach the step of installing the components of the requirements.txt, and this error occurs only on python virtual environment.
Error:

It appears you are missing some prerequisite to build the package from source.
You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.
For further information please check the 'doc/src/install.rst' file (also at
<http://initd.org/psycopg/docs/install.html>).

----------------------------------------
ERROR: Failed building wheel for psycopg2
I have tried to install different versions of the psycopg2 manually without success. If I don't use the virtual environment, there is no error and the installation process is totally successful.
pip install psycopg2-binary for ubuntu and pip install psycopg2 for windows
