The above exception was the direct cause of the following exception:

    First install python 3.6.5, then run

    pip install mysqlclient==1.3.12
sudo apt-get install python-dev default-libmysqlclient-dev
sudo apt-get install python3-dev
pip install mysqlclient

    Assume you are activating Python 3 venv

    brew install mysql
pip install mysqlclient

    You will need some additional libraries installed.

    Please refer to its project description: https://pypi.org/project/mysqlclient/

    Linux

    Note that this is a basic step. I can not support complete step for build for all environment. If you can see some error, you should fix it by yourself, or ask for support in some user forum. Don’t file a issue on the issue tracker.

    You may need to install the Python 3 and MySQL development headers and libraries like so:

    • $ sudo apt-get install python3-dev default-libmysqlclient-dev build-essential # Debian / Ubuntu
    • % sudo yum install python3-devel mysql-devel # Red Hat / CentOS

    Then you can install mysqlclient via pip now:
    $ pip install mysqlclient

    Hope it helps!
