ImproperlyConfigured MySQL in Django

Question

settings.py:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'OPTIONS': {
            'read_default_file': 'my.cnf',
        },
    }
}

my.cnf:

[client]
database=fake
host=127.0.0.1
port=3306
user=fake
password=fake
default-character-set=utf8

These files are in the same directory of my Django project. (The actual my.cnf has real credentials). I have installed mysqlclient. However, when I try to runserver I get the error

What configuration step(s) have I missed or farked up?

This looks like a possible duplicate of this question and this one

It looks like the library is not where it should be. From your previous question it looks like you installed it at

/usr/local/mysql/

but Django is expecting it to be at /usr/lib/

Creating the symlinks like in the other questions should fix this for you:

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib

sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql

Thanks. Looks like I still have a few more hurdles to cross, but this answer got me past THAT error message.
