Я использую MacOS 10.13.1 и Python версии 3.7.2. Я использовал pip3 install mysqlclient для установки mysqlclient, и он прошел успешно:
MacBook-Air:~ user$ pip3 install mysqlclient

pip3 list подтверждает, что версия 1.4.5 mysqlclient установлена.
Однако при запуске python3 manage.py makemigrations в каталоге, содержащем мой проект, появляется эта ошибка:
MacBook-Air:averages user$ python3 manage.py shell
