(python) Error while installing psycopg2 Ubuntu 20.04

I need to use psycopg2 package in python, Im trying to install it but I keep getting an error message while doing it. Not sure what the problem is since I've already installed pip.
This is the command I'm trying to run:
(venv) daniel#daniel-G5-5587:~/PycharmProjects/MIA_practica1$ pip3 install psycopg2
Any ideas? I'm attempting to Connect to PostgreSQL from Python.
I'm using Pycharm.
The error message I get is the following:
Collecting psycopg2

Please note that I have already checked out many questions opened for this same issue. But none of the suggested fix working for me.
Please help

This Issue is fixed now for me and for that I did 2 things:
1 - Installed wheel package
pip3 install wheel
2 - I followed this thread - Git is not working after macOS Update (xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools)

try to install the latest version of mysqlclient
mysqlclient==2.0.3
version 2.0.3 worked for me in python 3.9 (win)

How can I fix this : ERROR: Command errored out with exit status 1 : when trying to "pip install psycopg2"

I'm trying to connect Postgresql to my Django app
, I know that I should Install psycopg2 using pip
"Note: I read other questions and answers in stackoverflow and the other websites but I couldn't fix my problem with their solutions"
But I throw an ERROR like this:

Looks like you don't have openssl installed. Try brew install openssl
If you're still getting the error when openssl is installed you'll probably need to:
brew unlink openssl && brew link openssl --force
and then run the export LDFLAGS and export CPPFLAGS comands it outputs.

Unable to install TA-Lib on Ubuntu
I've spent hours on this and googling it to no avail. Does anyone have a solution? Thanks

I solved this issue by upgrading to Ubuntu 18.04 LTS. I had conflicts between Python 2.7 and 3.5/3.6.
After upgrading I changed the alias to python3 using nano ~/.bashrc and adding line alias python = python3.
Then installed TA-lib by running command:
python3 -m pip install TA-lib
Now everything is working fine. Thanks
