将Laravel 5.1升级到5.2时出现致命错误

Question

我正在遵循5.1到5.2 的官方升级指南.第一小节说:

如果要安装Laravel 5.2的beta版,请添加 "minimum-stability": "beta"到composer.json文件中.

更新您的composer.json文件以指向laravel/framework 5.2.*.

添加symfony/dom-crawler ~3.0和symfony/css-selector ~3.0你composer.json文件的要求-DEV部分.

现在,在我介绍上述更改并运行后composer update,我收到以下错误:

PHP Fatal error:  Class 'Illuminate\Routing\ControllerServiceProvider' not found 
in /home/vagrant/Code/myproject/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146

和

[Symfony\Component\Debug\Exception\FatalErrorException]
Class 'Illuminate\Routing\ControllerServiceProvider' not found

和

[RuntimeException]
Error Output: PHP Fatal error:  Class 'Illuminate\Routing\ControllerServiceProvider' not found in /home/vagrant/Code/myproject/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146

更新完成后抛出错误,并发生"生成自动加载文件".

可能有什么问题？

它看起来不像自定义包问题,而是核心问题.我是否应该继续使用升级指南并在composer update所有调整后运行以适应新的框架版本？

UPDATE

composer dump-autoload之后运行不会抛出上述错误.但仍然令人困惑.

Answer 1

没有Illuminate\Routing\ControllerServiceProvider了.

如果我是你,我会比较我的app项目https://github.com/laravel/laravel/commits/develop,如果你看看https://github.com/laravel/laravel/blob/develop/config/app.php你会看到Laravel 5.2的默认提供者:

Illuminate\Auth\AuthServiceProvider::class,
Illuminate\Broadcasting\BroadcastServiceProvider::class,
Illuminate\Bus\BusServiceProvider::class,
Illuminate\Cache\CacheServiceProvider::class,
Illuminate\Foundation\Providers\ConsoleSupportServiceProvider::class,
Illuminate\Cookie\CookieServiceProvider::class,
Illuminate\Database\DatabaseServiceProvider::class,
Illuminate\Encryption\EncryptionServiceProvider::class,
Illuminate\Filesystem\FilesystemServiceProvider::class,
Illuminate\Foundation\Providers\FoundationServiceProvider::class,
Illuminate\Hashing\HashServiceProvider::class,
Illuminate\Mail\MailServiceProvider::class,
Illuminate\Pagination\PaginationServiceProvider::class,
Illuminate\Pipeline\PipelineServiceProvider::class,
Illuminate\Queue\QueueServiceProvider::class,
Illuminate\Redis\RedisServiceProvider::class,
Illuminate\Auth\Passwords\PasswordResetServiceProvider::class,
Illuminate\Session\SessionServiceProvider::class,
Illuminate\Translation\TranslationServiceProvider::class,
Illuminate\Validation\ValidationServiceProvider::class,
Illuminate\View\ViewServiceProvider::class,
/*
 * Application Service Providers...
 */
App\Providers\AppServiceProvider::class,
App\Providers\AuthServiceProvider::class,
App\Providers\EventServiceProvider::class,
App\Providers\RouteServiceProvider::class,

Answer 2

在现有项目的5.1到5.2更新中,我们发现composer update在删除提供者的行之前和之后运行

Illuminate\Routing\ControllerServiceProvider::class Illuminate\Foundation\Providers\ArtisanServiceProvider::class

是完成laravel更新的必要序列.

之前运行将允许laravel下载和更新当前框架库依赖项,然后在删除后运行(编写器能够完成而没有问题)

我们还发现.env文件中的任何值都不能包含空格,并且必须用引号括起来才能工作.

Answer 3

从config/app.php中删除两个服务提供程序

Illuminate\Foundation\Providers\ArtisanServiceProvider::class,
 Illuminate\Routing\ControllerServiceProvider::class,

Answer 4

更新config /下的app.php文件解决了一个问题,但是引入了bootstrap/cache文件夹,你可能会继续遇到同样的错误.

我运行了作曲家更新在删除缓存文件之前,我一直遇到同样的错误.确保首先删除bootstrap/cache/services.php文件.

可能有一个工匠命令,但我完全错过了文档中的这一步.
