我正在遵循正式文档以安装Sonata Media Bundle，我认为直到使用此命令的步骤才能使用：
php bin/console sonata:easy-extends:generate --dest=src SonataMediaBundle
然后我将new ApplicationSonataMediaBundleApplicationSonataMediaBundle(),添加到AppKernel.php。
在这些步骤之后，我尝试输入Mi Admin（Localhost：8000/Admin），但会引发此错误：
尝试从命名空间"应用程序 sonata mediaBundle"加载类"应用程序"。 您是否忘记了另一个名称空间的"使用"语句？
我尝试执行php bin/console doctrine:schema:create（或更新），并且错误继续：
ubuntu@ubuntu-xenial:/workdir/Testing$ php bin/console doctrine:schema:update --force
PHP Fatal error: Uncaught SymfonyComponentDebugExceptionClassNotFoundException: Attempted to load class "ApplicationSonataMediaBundle" from namespace "ApplicationSonataMediaBundle".
Did you forget a "use" statement for another namespace? in /workdir/Testing/app/AppKernel.php:32

我验证了路线是正确的，并且像文档一样遵循步骤，我一直在通过Internet寻找答案，并找到了任何东西。请帮助！
我尝试执行没有--dest=src的php bin/console sonata:easy-extends:generate --dest=src SonataMediaBundle，以将文件夹放入应用程序/，但错误仍在...

编辑：
我认为问题是易于扩展，因为我尝试安装分类捆绑包，并且同样的情况发生，当前的Symfony版本是否支持Easy-Extends？也许是因为奏鸣曲用户捆绑包与当前版本不兼容（我也尝试过）...

您需要以类似的方式在AppBundle中添加自动加载器定义。
我了解，新捆绑包是在路径src/Application/Sonata/MediaBundle下生成的，因此是：
"autoload": {
"psr-4": {
"AppBundle\": "src/AppBundle"
"ApplicationSonataMediaBundle\": "src/Application/Sonata/MediaBundle"
},
"classmap": [
"app/AppKernel.php",
"app/AppCache.php"
]
},
