Errors installing mysqlclient on Max OSX - mysql

Question

I am trying to install mysqlclient on Mac OSX, as required by Django to use MySql rather than sqlite DB.
I originally tried pip3 install mysqlclient but I was getting an error like this:
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/3f/1z_bg4h52lz8n0_gc1mp7gwh0000gn/T/pip-install-em4vq6dr/mysqlclient/
I have done a lot of Googling and tried so many suggestions (this appears a common issue), and I've ended up with even more of a mess of an error message now:

Anybody have any suggestions as to where I'm going wrong?
Using Python 3.6
Thanks

Answer 1

Have fixed it based on this post - https://github.com/PyMySQL/mysqlclient-python/issues/169#issuecomment-306821834 - but I only did this bit:
ran brew info openssl
than entered the following as two separate commands
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
Then:
pip3 install mysqlclient
