when I run

or

pip3 install -r requirements.txt 

keep on getting the following error

If I follow this procedure by removing mysqlclient==1.4.6 from the requirements.txt file and try

sudo apt-get install mysqlclient 

I get

E: Unable to locate package mysqlclient

In order to fix it, I had to run first

sudo apt-get install python-dev default-libmysqlclient-dev 

and

sudo apt-get install python3-dev 

and only then install the requirements.

Apparently, it was some silly issue related to gcc.

sudo apt install gcc 

The above command should fix everything.
