安装后Symfony 2.8.1错误

我正在使用Symfony 2.8.1并使用WAMP Server 2,Apache 2.4.2和PHP 5.4.3在Windows 8上工作 我已经使用命令工具成功安装了Symfony,但是当我尝试访问URL时http:// localhost /Symfony/web/app_dev.php/我收到此错误消息:

FatalErrorException in ProxyGenerator.php line 62: Parse Error: syntax error, unexpected 'class' (T_CLASS), expecting identifier (T_STRING)

然后是这个错误列表:

in ProxyGenerator.php line 62

在ProxyGenerator.php的第62行:

protected $placeholders = [
    'baseProxyInterface'   => Proxy::class,
    'additionalProperties' => '',
];

问题似乎是这样的:

Proxy::class

当我把它改成那样:

'Doctrine\Common\Proxy\Proxy'

有用 !

我想知道发生了什么,如果我做出的改变是真实的解决方案.

有什么想法吗 ？谢谢.

这是一个PHP版本的问题.你需要至少PHP 5.5.

这是因为ProxyGenerator使用static class关键字进行类名解析.

因此,将您的Wamp服务器更新为PHP> 5.5并且您应该好好去!

您可以运行composer update以重新安装与PHP版本兼容的供应商库版本.
