运行 composer 时 Symfony 的供应商导致自动加载器 psr-4 警告

Question

多年来，每当运行 composer install:

时，我都会收到这些警告

Generating optimized autoload files (authoritative) Class Sensio\Bundle\FrameworkExtraBundle\Tests\DependencyInjection\AddParamConverterPassTest located in ./vendor/sensio/framework-extra-bundle/Tests/DependencyInjection/Compiler/AddParamConverterPassTest.php does not comply with psr-4 autoloading standard. Skipping. Class Sensio\Bundle\FrameworkExtraBundle\Tests\DependencyInjection\AddExpressionLanguageProvidersPassTest located in ./vendor/sensio/framework-extra-bundle/Tests/DependencyInjection/Compiler/AddExpressionLanguageProvidersPassTest.php does not comply with psr-4 autoloading standard. Skipping. Class Sensio\Bundle\FrameworkExtraBundle\Tests\Request\ParamConverter\ArgumentNameConverterTest located in ./vendor/sensio/framework-extra-bundle/Tests/Request/ArgumentNameConverterTest.php does not comply with psr-4 autoloading standard. Skipping. Class Doctrine\Bundle\MigrationsBundle\Tests\DependencyInjection\DoctrineCommandTest located in ./vendor/doctrine/doctrine-migrations-bundle/Tests/Command/DoctrineCommandTest.php does not comply with psr-4 autoloading standard. Skipping.

我怎样才能摆脱这些由供应商引起的警告？

如果代码不在您的控制之下（供应商代码），那么您无法真正解决问题。或者：

你升级你的依赖项（这可能很困难和有问题，取决于你的项目，但最终是最好的前进方式）
您 将 Composer 降级 到不会引发该警告的版本。这不是推荐的行动方案。你至少会失去性能，并且错过了更高版本的错误修复。
您忽略警告，因为警告不是错误，在安装过程中而不是在应用程序运行时显示的警告更是如此。
