Class Not found in AppKernel.php
提问by Jason Lin
I'm trying to deploy my Symfony2 project. When I run the command
我正在尝试部署我的 Symfony2 项目。当我运行命令时
php app/console cache:clear --env=prod --no-debug
I get the following error:
我收到以下错误：
PHP Fatal error: Class 'Acme\MainBundle\AcmeMainBundle' not found in /var/www/html/app/AppKernal.php on line 24
This is the in AppKernal.php
这是在 AppKernal.php
public function registerBundles()
{
$bundles = array(
...
new Acme\MainBundle\AcmeMainBundle(),
);
...
}
It seems like there's a problem with the namespace?
好像命名空间有问题？

If you are getting a bundle not found error in Symfony, in composer.json, modify the psr-4section under autoloadsection like this.
如果您在 Symfony 中遇到 bundle not found 错误，请在 composer.json 中像这样修改psr-4部分下的autoload部分。
"autoload": {
"psr-4": {
"": "src/"
},
},
By doing so, you don't have to explicitly add the new bundle namespaces when you create a new bundle.
通过这样做，您不必在创建新包时显式添加新包命名空间。

If this happened in Symfony 3 (I haven't tested this in symfony 2),
如果这发生在 Symfony 3（我没有在 symfony 2 中测试过），
Make sure your bundle is registered in AppKernal.php as:
public function registerBundles() { $bundles = array( ... new YourBundle\YourBundle(), ); ... }Check if you've updated composer.json
"autoload": { "psr-4": { "AppBundle\": "src/AppBundle", "YourBundle\": "src/YourBundle" }, "classmap": [ "app/AppKernel.php", "app/AppCache.php" ] },Run
composer updatefrom your console
确保您的包在 AppKernal.php 中注册为：
public function registerBundles() { $bundles = array( ... new YourBundle\YourBundle(), ); ... }检查您是否已更新 composer.json
"autoload": { "psr-4": { "AppBundle\": "src/AppBundle", "YourBundle\": "src/YourBundle" }, "classmap": [ "app/AppKernel.php", "app/AppCache.php" ] },composer update从你的控制台运行

Had the same problem after adding a bundle with the code generator with Symfony 3.2. I had to add this new bundle in the autoload section of composer.json after the AppBundle :
在使用 Symfony 3.2 添加带有代码生成器的包后遇到了同样的问题。我必须在 AppBundle 之后的 composer.json 的自动加载部分中添加这个新包：
(...)
"autoload": {
"psr-4": {
"AppBundle\": "src/AppBundle",
"CoreBundle\": "src/CoreBundle"
},
(...)

Turns out i needed to add this to the autoloader. Thanks @DevZer0's comment.
结果我需要将它添加到自动加载器中。感谢@DevZer0 的评论。
$loader->add('Acme', __DIR__ . '/../src');
$loader->add('Acme', __DIR__ . '/../src');

Removing the whole folder wasn't very convincing for me, so I tried doing just the following and it worked:
删除整个文件夹对我来说不是很有说服力，所以我尝试只执行以下操作并且它有效：
$ composer update
Then I checked it with:
然后我检查了它：
$ php bin/console assets:install web --symlink
$ php bin/console cache:clear

I've experience all the above errors before, but I found a similar issue when running php app/console doctrine:migrations:status.
我以前遇到过上述所有错误，但在运行php app/console doctrine:migrations:status.
The issue was that I had not imported a constant which was being used as part of an annotation. For example:
问题是我没有导入用作注释一部分的常量。例如：
/**
* Either "OUTBOUND" (we send out) or "INBOUND" (we receive).
*
* @var string
*
* @ORM\Column(name="Direction", type="string", length=20, nullable=true)
*
* @Assert\Choice(
* choices = {BatchDirections::OUTBOUND,BatchDirections::INBOUND},
* message = "Choose a valid direction."
* )
*/
private $Direction = BatchDirections::INBOUND;
I hadn't imported the BatchDirections file.
我没有导入 BatchDirections 文件。
Resolving the import with use Nora\BatchBundle\Constants\BatchDirections;fixed the issue.
通过use Nora\BatchBundle\Constants\BatchDirections;修复问题解决导入。
