    This error happens when a connection couldn’t be established. In some cases you’ll need to have the the host set to 127.0.0.1, this all depends on your dev setup.

    If you’re running MAMP you can also alias the MySQL socket like so:

    $ sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /var/mysql/mysql.sock

    As the troubleshooting section describes sometimes you need to create the MySQL directory first:

    $ sudo mkdir /var/mysql
$ sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /var/mysql/mysql.sock
