Question

我在Symfony中收到以下错误消息：

Parse error: syntax error, unexpected '\' (T_NS_SEPARATOR), expecting identifier (T_STRING)

当我执行DoctrineMigrations时，这一行出现了吗？

我该怎么调试呢？

这是完整的痕迹：

PHP Fatal error:  Uncaught Symfony\Component\Debug\Exception\FatalThrowableError: Parse error: syntax error, unexpected '\' (T_NS_SEPARATOR), expecting identifier (T_STRING) in /Library/WebServer/Documents/hrd_3/var/cache/dev/appDevDebugProjectContainer.php:7087

更新：在7087的调试容器中：

class VichUploaderBundleHandlerDownloadHandler_00000000110518fa000000015e248fd4966f7bb604f68fe14d5ab23e4a657cd2 extends \\Vich\UploaderBundle\Handler\DownloadHandler implements \\ProxyManager\Proxy\VirtualProxyInterface
{

如果我禁用了这个模块，那么另一个类就会出现这个问题...就像随机一样。

我发现问题是由新的zendframework v3.0.3引起的 - 请参阅https://github.com/symfony/symfony/issues/9815

所以对于目前的快速修复，只需添加

＆＃34; zendframework / zend-code＆＃34;：＆＃34; 3.0.2＆＃34;

同样的错误出现在symfony / framework-bundle版本2.8.13，文件DependencyInjection / FrameworkExtension.php中，第374行：

$container->setParameter('router.cache_class_prefix', $container->getParameter('kernel.container_class'));

版本2.8.12没问题：

$container->setParameter('router.cache_class_prefix', $container->getParameter('kernel.name').ucfirst($container->getParameter('kernel.environment')));

在PHP 5.6.26上测试......
