Symfony:如何调试意外的'\'(T_NS_SEPARATOR)

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)  

例如,当我执行DoctrineMigrations时,这一行出现了吗？

我怎么调试这个？

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
{

如果我禁用此模块,那么另一个类将有这个问题......就像随机.

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,只需添加即可

"zendframework/zend-code":"3.0.2"
