php - 未找到类 'Doctrine\Common\Annotations\AnnotationRegistry'

Question

我第一次使用 Doctrine 时遇到了错误。我前一天晚上离开了我的项目，这个错误不存在，在一台新机器上启动了 web 服务器并遇到了这个错误。

Fatal error: Uncaught Error: Class 'Doctrine\Common\Annotations\AnnotationRegistry' not found in D:\website\vendor\doctrine\orm\lib\Doctrine\ORM\Configuration.php:156 Stack trace: #0 D:\website\vendor\doctrine\orm\lib\Doctrine\ORM\Tools\Setup.php(72): Doctrine\ORM\Configuration->newDefaultAnnotationDriver(Array, true) #1 D:\website\src\setup.php(16): Doctrine\ORM\Tools\Setup::createAnnotationMetadataConfiguration(Array, true) #2 D:\website\src\bootstrap.php(6): include('C:\Users\admin\...') #3 D:\website\public\index.php(7): require('C:\Users\admin\...') #4 {main} thrown in D:\website\vendor\doctrine\orm\lib\Doctrine\ORM\Configuration.php on line 156

我试过 composer update和 composer install ，两者都没有帮助。

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

$paths = array(ROOT . "/src/Database/Modals");
$config = $container->get('App\Providers\Config');

$dbParams = array(
    'driver'   => $config->get('database.driver'),
    'user'     => $config->get('database.user'),
    'password' => $config->get('database.password'),
    'dbname'   => $config->get('database.name'),
);

$entityConfig = Setup::createAnnotationMetadataConfiguration($paths, true);
$entityManager = EntityManager::create($dbParams, $entityConfig);

这行代码似乎抛出了异常。

$entityConfig = Setup::createAnnotationMetadataConfiguration($paths, true);

@martin-barker 上面的评论对我有用:

composer require doctrine/annotations
