Laravel Dusk 报错：Facebook\WebDriver\Exception\UnknownServerException: unknown error: cannot get automation extension 的处理办法

报错如下：

There was 1 error:

1) Tests\Browser\OrderTest::a_user_can_see_item_title
Facebook\WebDriver\Exception\UnknownServerException: unknown error: cannot get automation extension
from unknown error: page could not be found: chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/_generated_background_page.html
  (Session info: chrome=57.0.2987.133)
  (Driver info: chromedriver=2.27.440174 (e97a722caafc2d3a8b807ee115bfb307f7d2cfd9),platform=Mac OS X 10.12.3 x86_64) 

错误原因

chrome 升级到 v57，而 dusk v1.0.11 之前版本自带的 chromedriver 2.27 并不支持此版本的 chrome

两种解决办法

1. 手动从 这里下载 chromedriver v2.28，放入 vendor/laravel/dusk/bin 路径下；
2. composer update 更新 Laravel Dusk 到最新版本
