php - ClassNotFoundException : Attempted to load class "FOSUserBundle" from namespace "FOS\UserBundle"

Question

(在 Windows 10 上使用 WampServer。)

我按照官方文档在 Symfony 上安装 Sonata User Bundle。

我收到以下错误消息

(1/1) ClassNotFoundException Attempted to load class "FOSUserBundle" from namespace "FOS\UserBundle". Did you forget a "use" statement for another namespace?

AppKernel.php

当我到达从运行开始的第 2.5 步时

php bin/console sonata:easy-extends:generate SonataUserBundle -d src

我得到

Fatal error: Class 'FOS\UserBundle\FOSUserBundle' not found.

根据评论中的要求:composer.json 的自动加载部分

"autoload": {
    "psr-4": {
        "AppBundle\\": "src/AppBundle"
    },
    "classmap": [ "app/AppKernel.php", "app/AppCache.php" ]
},

Answer 1

在 composer.json 中

 "autoload": {
        "psr-0": { 
            "": "src/", 
            "Application": "app/" 
        }
    },

比更新 Composer :

composer update

如果这不起作用，请尝试通过以下命令修复捆绑包:

php app/console sonata:easy-extends:generate --dest=src SonataMediaBundle

扩展基本用户 FosUser :

class Myusers extends BaseUser
{
}

在 config.yml

fos_user:
    user_class: MyBundle\Entity\Myusers
