Answer 1

I think libffi-dev libary file is missing in your system/server. use the below command in order to check library installed or not

apt-cache search libffi

to install libffi-dev

sudo apt-get install -y libffi-dev

After that try

pip3 install mysqlclient

Approach 2

sudo apt-get install python-dev default-libmysqlclient-dev
sudo apt-get install python3-dev
pip install mysqlclient
