报错：

 Fatal error: Declaration of App\DataFixtures\AppFixtures::load(Doctrine\Common\Persistence\ObjectManager $manager) must be compatible with Doctrine\Common\DataFixtures\FixtureInterface::load(Doctrine\Persistence\ObjectManager $manager) in E:\wamp64\www\vrPlatform\src\DataFixtures\AppFixtures.php on line 8
 

问题背景：

symfony项目 composer update 后

解决：

1. 删除 \src\DataFixtures目录
2. bin/console cache:clear

3. use Doctrine\Common\Persistence\ManagerRegistry;
   改为：
   use Doctrine\Persistence\ManagerRegistry;
