PHP致命错误:未捕获错误:调用未定义的方法PHPUnit\Util\Configuration::getExtensionConfiguration()

我想按照这里的说明https://laravel.com/docs/5.6/testing.在环境部分这里我做了什么.

php artisan env --env=testing

然后跑

phpunit

但在那之后,这条消息就出现了

PHP Fatal error:  Uncaught Error: Call to undefined method PHPUnit\Util\Configuration::getExtensionConfiguration() in /mnt/c/projects/www/janicalizdotcom/vendor/phpunit/phpunit/src/TextUI/TestRunner.php:953
Stack trace:

那什么意识？我该怎么办呢？

自从第一次进行laravel测试以来,我不得不提出想法

如果只是phpunit工作意味着您有PHPUnit的全局安装.您可能想要使用vendor/bin/phpunit.
