Question

我运行了composer update命令，它从symfony 2.1.7更新到symfony 2.1.8。这是我的问题开始的地方。现在，当我尝试运行任何symfony控制台命令时，我收到如下错误：

 Fatal error: Class 'Symfony\Component\Console\Input\ArgvInput' not found in C:\xampp\htdocs\myproject\app\console on line 16

当我在浏览器中运行我的项目时，我收到此错误：

Fatal error: Class 'Symfony\Component\ClassLoader\DebugClassLoader' not found in C:\xampp\htdocs\myproject\app\bootstrap.php.cache on line 542

以前一切正常。

我该如何解决这个问题？

这是我的composer.json：

{

"description": "The \"Symfony Standard Edition\" distribution",
"autoload": {
    "psr-0": { "": "src/" }
},

    ],

    ]

Answer 1

如果有人在sensio发布包= 5时出现相同的错误，那么您的问题应该是Fatal error: Class 'Symfony\Component\Console\Input\ArgvInput' not found in app/console on line 16

Answer 2

尝试更新作曲家（https://getcomposer.org/doc/03-cli.md#self-update）

composer self-update

清除其缓存，对于Windows C:\Users\<user>\AppData\Roaming\Composer（https://getcomposer.org/doc/03-cli.md#composer-home）

然后再次运行更新。

手动删除symfony2缓存文件夹可能会有所帮助。

Answer 3

您的引导程序文件没有正确重建，composer.json文件应该有一个脚本条目，可以确保为您完成此任务（除非您使用--no-scripts标志运行）。

"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"
    ]
}

您可以通过在symfony目录中运行以下命令来手动运行构建引导程序文件的脚本：

php /vendor/sensio/distribution-bundle/Sensio/Bundle/DistributionBundle/Resources/bin/build_bootstrap.php

从symfony 2.1.7升级到symfony 2.1.8
