MySQL Issues when running via CLI

I was trying to get some resources working via CLI, so I created a "cli_test" method inside the "Test" controller, which just outputs a string. When I execute it, I get a database error. Here is the output:

$ clear
MacBooks-MacBook-Air:htdocs me$ php index.php test cli_test
Xdebug requires Zend Engine API version 220121212.
The Zend Engine API version 220131226 which is installed, is newer.
Contact Derick Rethans at http://xdebug.org/docs/faq#api for a later version of Xdebug.

A PHP Error was encountered

Severity: WarningMessage:  mysqli::real_connect(): (HY000/2002): No such file or directoryFilename: /Users/me/PhpstormProjects/SOME-App/htdocs/system/database/drivers/mysqli/mysqli_driver.phpLine Number: 135

Heres the MySQL config:

PHP Code:

$active_group = 'development';

$query_builder = TRUE;

$db['development'] = array(
    'dsn'        => '',
    'hostname'      => 'localhost',
    'username'      => 'root',
    'password'      => 'Password1',
    'database'      => 'sasset',
    'dbdriver'      => 'mysqli',
    'dbprefix'      => 'sassetdb_',
    'pconnect'      => FALSE,
    'db_debug'      => TRUE,
    'cache_on'      => FALSE,
    'cachedir'      => '',
    'char_set'      => 'utf8',
    'dbcollat'      => 'utf8_general_ci',
    'swap_pre'      => '',
    'encrypt'       => FALSE,
    'compress'      => FALSE,
    'stricton'      => FALSE,
    'failover'      => [],
    'save_queries'  => TRUE
); 


However whenever visit the page via the browser, it works perfectly fine..

I looked at line 135 in the mysqli_driver.php file, its

PHP Code:

return $mysqli->real_connect($hostname, $this->username, $this->password, $this->database, $port, $socket, $client_flags) ? $mysqli : FALSE; 


Could it be the $socket?

Edit: When I output the socket, its empty/null, so I doubt thats it...

I tried a simple CLI call on another CI instance that I have running locally. When its not configured to use the database, it works fine, when I do have a database configured, it throws the error.

is there something special I need to do to get CI working with the DB on the command line?

I found it, looks like I had to specify the mysqli.default_socket in the php.ini
