PHPUnit停止运行

周末过后，我又犯了以下错误：

Fatal error: Uncaught Error: Class 'PHPUnit\Runner\TestSuiteSorter' not found in /Users/piersb/Development/Den/dezeenjobs/_project/vendor/phpunit/phpunit/src/TextUI/TestRunner.php on line 1143

但谷歌并没有给我任何关于什么是TestSuiteSorter以及为什么它现在突然开始流行的有用结果

已运行composer更新，没有新闻

我确实升级了Wordpress和Woocommerce，但在这之前（测试是绿色的）回滚到提交并没有帮助；它只是给了我一个关于TestSuiteSorter的稍微不同的错误消息

Warning: include(/Users/piersb/Development/Den/dezeenjobs/_project/vendor/composer/../phpunit/phpunit/src/Runner/TestSuiteSorter.php): failed to open stream: No such file or directory in /Users/piersb/Development/Den/dezeenjobs/_project/vendor/composer/ClassLoader.php on line 444

有人有线索吗

新信息：引入问题的提交是当我从通过命令行安装phpunit切换到通过composer安装phpunit时。检查composer.json文件，看起来phpunit的版本是通过WP_Mock依赖项引入的

---

此版本正在调用TestSuiteSorter类，但该文件似乎不存在。

最后，我将我的composer文件要求更新到此版本

{
    "require": {
        "intervention/image": "^2.3",
        "10up/wp_mock": "0.3.0",
        "phpunit/phpunit": "^7.2" // this is the new line
    }
}

然后删除我的供应商目录并运行

composer安装

和

composer更新

现在一切正常。胡萨
