Installing mysqlclient for mariadb on mac os for python3

The problem is here since mariadb 10.2.x, with mariadb 10.1.23 I have no problem to install mysqlclient.

So with mariadb 10.2.x we needs to install mariadb-connector-c:

brew unlink mariadb

brew install mariadb-connector-c
ln -s /usr/local/opt/mariadb-connector-c/bin/mariadb_config /usr/local/bin/mysql_config

pip install mysqlclient

rm /usr/local/bin/mysql_config
brew unlink mariadb-connector-c
brew link mariadb

UPDATE: the bug is fixed in mysqlclient (see https://github.com/PyMySQL/mysqlclient-python/pull/177) but not yet released

SOLVE:

pip uninstall mysqlclient
pip install -U git+git://github.com/PyMySQL/mysqlclient-python
