当我尝试在项目中运行 全局PHPUnit 时，我遇到了一个令人费解的错误。
我的系统级 PHPUnit版本是7.2.6 ，而我的 PHP版本是7.2.7。
这是我得到的错误：
vars = vars.drop_duplicates()
有趣的是，它在我运行PHPUnit 7.2.6 by Sebastian Bergmann and contributors.
PHP Fatal error: Uncaught Error: Call to undefined method PHPUnit\Util\Configuration::hasValidationErrors() in /Users/ronald/Sites/painting/vendor/phpunit/phpunit/src/TextUI/TestRunner.php:337

时有效，但在全局PHPUnit上无效。我可以在我的任何项目中运行全局版本，并且可以正常运行，所以我不确定问题出在哪里。
最后，这是我的phpunit.xml文件。

永远不要将全局PHPUnit安装与在本地项目，Composer安装的PHPUnit混合使用。
