Creating the Addon

The first step in creating a new Xenforo Addon is creating the addon within the Xenforo dev environment with the following command: php cmd.php xf-addon:create.

Last night I set up a development environment for Xenforo using (XAMPP)[]. I was able to install Xenforo and create an addon without a problem on Windows.

However, when I tried to do this on Mac I got the following error:

An exception occurred: [XF\Db\Exception] No such file or directory in src/XF/Db/Mysqli/Adapter.php on line 173

#14 src/XF/Cli/Runner.php(50): XF::setupApp('XF\\Cli\\App')
#15 cmd.php(15): XF\Cli\Runner->run()
#16 {main}

Turns out that the problem was in my config.php file where I had host configured as localhost:

$config['db']['host'] = 'localhost';

On a hunch, I figured I would try the following:

$config['db']['host'] = '';

And it worked! Now I’m able to create new addons on my Mac without a problem.
