Symfony 4 抛出 UndefinedMethodException 异常

Question

从今天开始我就遇到了这个奇怪的问题。我目前正在开发一个以 Symfony 4 为基础的系统。在本地，它工作得很好，没有任何问题。但是，当我将代码推送到 Azure（完成后我将在其中部署并提供服务）时，我在 prod.log:

上收到以下错误

[2018-11-28 19:19:26] php.CRITICAL: Call to undefined method Doctrine\Common\Annotations\PhpParser::write() {"exception":"[object] (Symfony\Component\Debug\Exception\FatalThrowableError(code: 0): Call to undefined method Doctrine\Common\Annotations\PhpParser::write() at D:\home\site\wwwroot\vendor\symfony\http-foundation\Session\Storage\Handler\StrictSessionHandler.php:64)"} []
[2018-11-28 19:19:26] request.CRITICAL: Uncaught PHP Exception Symfony\Component\Debug\Exception\UndefinedMethodException: "Attempted to call an undefined method named "write" of class "Doctrine\Common\Annotations\PhpParser"." at D:\home\site\wwwroot\vendor\symfony\http-foundation\Session\Storage\Handler\StrictSessionHandler.php line 64 {"exception":"[object] (Symfony\Component\Debug\Exception\UndefinedMethodException(code: 0): Attempted to call an undefined method named \"write\" of class \"Doctrine\Common\Annotations\PhpParser\". at D:\home\site\wwwroot\vendor\symfony\http-foundation\Session\Storage\Handler\StrictSessionHandler.php:64)"} []

我已经清除了作曲家缓存、Symfony 缓存，删除了整个 vendor 目录和运行 composer update（两次）希望它能解决问题。

除了更改我的代码外，我没有更改任何其他内容。我到处搜索了这个 Doctrine\Common\Annotations\PhpParser 包，但我找不到任何与它真正相关的东西。这是我的 composer.json:

        }
    }
}

这可能是某些必需软件包的问题吗？

Answer 1

原来我少了一个包裹。 @EquaPro 在评论中指出 PhpParser 是 doctrine/common 包的一部分，我的 composer.json 中的任何包都没有安装它。

可能的原因：当我在学习Security/Authentication教程时，我决定不安装Doctrine，因为我不打算通过安装symfony/orm-pack来使用it.Fixed它。
