AppKernel.php奇怪的行为

Question

所以,我正在尝试创建一个新项目,但内核正在发生一些事情,我并不理解.每次当我生成新的Bundle并尝试创建控制器或任何东西时,会出现此错误:

PHP致命错误:未捕获的Symfony\Component\Debug\Exception\ClassNotFoundException:尝试从命名空间"ContactBoxBundle"加载类"ContactBoxBundle".您是否忘记了另一个命名空间的"use"语句？在/var/www/ContactBox/app/AppKernel.php:19堆栈跟踪:

第19行的/var/www/ContactBox/app/AppKernel.php中的Symfony\Bundle\FrameworkBundle\Console\Application-> ad

我以前在Symfony做过项目,它从未发生在我身上.有任何想法吗？我使用控制台命令"bin/console generate:bundle"生成了Bundle.它生成它应该的一切,默认控制器,模板和类,但由于这个错误,我无法进一步做这件事.有任何想法吗？

AppKernel.php

<?php

请帮帮忙,因此我疯了!

Answer 1

尝试从此更改您的composer.json文件:

"psr-4": {
    "AppBundle\\": "src/AppBundle"
 }

对此:

"psr-4": {
    "": "src/"
},

这样你就可以加载src下的所有Bundle.

像这样:

"psr-4": {
    "AppBundle\\": "src/AppBundle",
    "ContactBoxBundle\\": "src/ContactBoxBundle",
}

或者,您可以根据需要指定要加载的每个Bundle.

之后你需要从控制台制作:

composer dump-autoload
