Answer 1

It didn't worked for me too, but after clicking the link provided by #Suraj Virkar, I noticed that the command for installing is a little different. So instead of using
pip install flask-mysqldb
Just use
pip install Flask-MySQL
and i'm not really sure why but it worked! it must have someting to do with the versions i guess... oh and take note that you'll have to use
from flaskext.mysql import MySQL
to import it on your project instead of using
from flask_mysqldb import MySQL
Hope this helps...

Answer 2

try to install flask-mysqldb by the following method
Installation
pip install flask-mysqldb
if you get error or system cannot fetch wheel file of flask-mysqldb, then go to this link
where you can download wheel file and then run that wheel file.
If this also not working then first install mysqlclient
pip install mysqlclient
and then install flask-mysqldb.
