ReflectionException：类不存在 [英] ReflectionException: Class does not exist

问题描述

当我尝试运行作曲家时遇到了这个错误

I'm running into this error when I tried to run the composer

{
    "name": "zepluf/standard-edition",
    "description": "The \"ZePLUF Standard Edition\" distribution",
    "autoload": {
        "psr-0": { "": "src/" }
    },
    "require": {
        "php": ">=5.3.3",
        "symfony/symfony": ">=2.1",
        "symfony/framework-bundle": ">=2.1",
        "doctrine/orm": ">=2.2.3,<2.4-dev",
        "doctrine/doctrine-bundle": "1.0.*",
        "twig/extensions": "1.0.*",
        "symfony/assetic-bundle": "2.1.*",
        "symfony/swiftmailer-bundle": "2.1.*",
        "symfony/monolog-bundle": "2.1.*",
        "sensio/distribution-bundle": "2.1.*",
        "sensio/framework-extra-bundle": "2.1.*",
        "sensio/generator-bundle": "2.1.*"
    },
    "scripts": {
        "post-install-cmd": [
            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile"
        ],
        "post-update-cmd": [
            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap",
            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache",
            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets",
            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile"
        ]
    },
    "minimum-stability": "dev",
    "extra": {
        "symfony-app-dir": "app",
        "symfony-web-dir": "web"
    }
}

似乎通过了一个空的类名进来，但是我不确定如何调试回溯跟踪以找到它的位置。

It seems like somehow an empty classname is passed in, but I'm not so sure how to do debug back trace to locate where it is.

推荐答案

似乎错误是因为我试图在依赖项编译器遍历中检索服务。我重写了代码，以避免不得不从那里检索服务。

It seems like the error was because I attempted to retrieve a service inside a dependency compiler pass. I rewrote my code to avoid having to retrieve service from there.
