php - 如何使用通过composer安装的包

Question

I've installed FactoryMuffin via composer. After installation, I ran composer dump-autload just to make sure I was using the latest stuff.

Now, when I try to use in my code something from the package I installed I can't. For instance:

use League\FactoryMuffin\Facade;

class APITest extends Sw_Test_PHPUnit_LibraryTestCase
{

    public function setUp()
    {
        $a = new FactoryMuffin();

        parent::setUp();
    }
}

When I hover over the new FactoryMuffin object instantiation, it says it cannot find its declaration.

If I hover over Facade in:

use League\FactoryMuffin\Facade;

it says

Undefined class Facade

and when hovering over:

use League\FactoryMuffin

it says

multiple implementations

I'm following all the steps listed in the documentation for FactoryMuffin, what am I missing?

Here's my composer file:

Try using as

use League\FactoryMuffin\Facade as FactoryMuffin;

FactoryMuffin::define('Message', array(
    'user_id'      => 'factory|User',
    'subject'      => 'sentence',
    'message'      => 'text',
    'phone_number' => 'randomNumber|8',
    'created'      => 'date|Ymd h:s',
    'slug'         => 'call|makeSlug|word',
), function ($object, $saved) {
    // we're taking advantage of the callback functionality here
    $object->message .= '!';
});
