【问题描述】：

我想部署 symfony2 应用程序。在 localhost 上完美运行，我的 web 目录的唯一区别是在 public_html 中，但是当我安装在我的 prod 服务器上时，在注册一些用户后，抛出了异常。看起来反序列化无法解码，我的实体“0:{}”：

ContextErrorException: Warning: Erroneous data format for unserializing 'CodeCats\PanelBundle\Entity\User' in /home/progress/domains/progress-checker.pl/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php line 869

** Mandatory requirements **

 OK       PHP version must be at least 5.3.3 (5.4.29 installed)

请在您的生产服务器上运行php app/check.php 并报告结果。服务器可能缺少必要的 php 扩展。

好的，这就是问题所在（以及可能的解决方案）：

顶部链接已损坏，答案不必要地埋在第二个链接中。将来，最好引用链接而不是仅仅出于这些原因提供来源。

【解决方案2】：

对于那些仍然遇到这个问题的人，更新教义/orm 依赖项是有效的。

我在 composer.json 中的新学说依赖行： "教义/orm": ">=2.2.3,

然后我照常从命令行更新作曲家：php composer.phar update

由于它是该错误的最佳 Google 结果，我将在此处粘贴肮脏的快速修复以让您更轻松地进行操作。

注意：几乎在所有情况下您都不应该像这样修改任何供应商文件。但是，如果您有一些由于某种原因无法解决的依赖问题，这里有一个窍门。

这是一个 Doctrine 错误，因此您应该稍微修改 Doctrine ORM 包。

将您的PHP_VERSION_ID 添加到

中的newInstance() 函数中

/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php

我的最终结果是这样的：

public function newInstance()
{
    // echo PHP_VERSION_ID; die();  // Uncomment this, in case you don't know your PHP_VERSION_ID
    if ($this->_prototype === null) {
        if (PHP_VERSION_ID === 50429 || PHP_VERSION_ID === 50513 || PHP_VERSION_ID === 50603 || PHP_VERSION_ID === 70009) { // This is the tricky line
            $this->_prototype = $this->reflClass->newInstanceWithoutConstructor();
        } else {
            $this->_prototype = unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name));
        }
    }

    return clone $this->_prototype;
}

我有同样的问题。我通过将 Composer.json 中的 "doctrine/orm" 包更新为 "~2.4" 版本然后运行来解决它：
作曲家更新学说/orm
从命令行。这应该只更新相关的包。在此刷新网页和/或再次登录之后，错误消失了。
希望这会有所帮助。
