安装Laravel黄昏后显示错误

Question

这是我的代码laravel黄昏：-

DuskTestCase.php     

namespace Tests;

use Laravel\Dusk\TestCase as BaseTestCase;
use Facebook\WebDriver\Remote\RemoteWebDriver;
use Facebook\WebDriver\Remote\DesiredCapabilities;

abstract class DuskTestCase extends BaseTestCase
{
    use CreatesApplication;


    public static function prepare()
    {
        static::startChromeDriver();
    }

    /**
     * Create the RemoteWebDriver instance.
     *
     * @return \Facebook\WebDriver\Remote\RemoteWebDriver
     */
    protected function driver()
    {
        return RemoteWebDriver::create(
            'http://localhost:8000', DesiredCapabilities::chrome()
        );
    }
}

ExampleTest.php     

namespace Tests\Browser;

use Laravel\Dusk\Browser;
use Tests\DuskTestCase;

class ExampleTest extends DuskTestCase
{
    /**
     * A basic browser test example.
     *
     * @return void
     */
    public function testBasicExample()
    {
        $this->browse(function (Browser $browser) {
            $browser->visit('/')
                    ->assertSee('Laravel');
        });
    }
}
