JMSDiExtraBundle can be conveniently installed via Composer. Just add the following to your composer.json file:
// composer.json
{
// ...
require: {
// ...
"jms/di-extra-bundle": "dev-master"
}
}
Then, you can install the new dependencies by running Composer’s update command from the directory where your composer.json file is located:
php composer.phar update
Now, Composer will automatically download all required files, and install them for you. All that is left to do is to update your AppKernel.php file, and register the new bundle:
<?php
// in AppKernel::registerBundles()
$bundles = array(
// ...
new JMS\DiExtraBundle\JMSDiExtraBundle($this),
new JMS\AopBundle\JMSAopBundle(),
// ...
);
