Hey! I also had the same trouble but this post : pipenv install mysqlclient on MacOSX | by Shan Dou | Medium saved my ass, just follow it, do the brew info openssl, locate a similar part like this:
Enter the three comands, close your terminal
open again, go where is your project without activating pipenv shell and run pipenv install mysqlclient
