I am deploying Django on DigitalOcean using MySQL and Apache. I am following a step-by-step tutorial on Youtube and everything is fine until when I start installing the python package mysql-client.

Here are the previous steps I took:

  1. sudo apt install python3-dev

  2. sudo apt install libmysqlclient-dev

  3. pip install mysqlclient

Here is the full error message I got from the terminal:

(verenv) root@verauto:/verauto# pip3 install mysqlclient

And here is my pip freeze:

beautifulsoup4==4.8.2
Django==2.2.5
django-bootstrap4==1.0.1
django-crispy-forms==1.7.2
django-debug-toolbar==2.1
Pillow==6.1.0
pytz==2019.3
soupsieve==1.9.5
sqlparse==0.3.0

Found the answer! Finally!

I needed to install libssl-dev.
