问题描述
将symfony / framework-bundle配方从4.4升级到5.1版本后，出现此错误：
Argument 2 passed to Symfony\Component\Routing\Loader\Configurator\RoutingConfigurator::__construct() must be an instance of Symfony\Component\Routing\Loader\PHPFileLoader,instance of Symfony\Component\Routing\Loader\AnnotationFileLoader given,called in /app/vendor/symfony/framework-bundle/Kernel/MicroKernelTrait.PHP on line 176
食谱进行了以下更改：
此外，我发现是否从vendor/symfony/routing/Loader/Configurator/RoutingConfigurator.PHP的构造函数中删除了PHPLoader typehint。一切开始工作
也许我忘记了什么？或者我如何在不更改供应商文件的情况下使它工作？
