Question

我按照 Easy Laravel 5 一书中提供的材料学习Laravel。所以我按照指示创建了应用，当我访问localhost:8000时，我看到了欢迎页面。

然后我给了名字改变命令：

php artisan app:name todoparrot

系统以Application namespace set!回复。但是现在当我重新加载localhost:8000时，我什么都没看到，服务该应用程序的终端给了我一长串错误：

PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Class todoparrot\Console\Kernel does not exist' in /media/common/htdocs/todoparrot/vendor/laravel/framework/src/Illuminate/Container/Container.php:776
Stack trace:

现在我甚至无法运行artisan，因为我一直遇到同样的错误。知道因为这个极其简单的变化可能会被打破吗？

Answer 1

重命名后尝试此命令：

composer dump-autoload

Composer在vendor/composer/目录中的自动加载文件中包含您的命名空间。当你改变任何你需要清除它并再次生成它时，该命令就可以了。

Answer 2

如果您运行以下命令，它将更改所有命名空间和路径到todoparrot。在你的情况下，没有找到Laravel＆＃34;类todoparrot \ Console \ Kernel不存在＆＃34;。确保命名空间已更改为todoparrot

php artisan app:name todoparrot

该命令将修改以下所有文件

modified:   app/Commands/Command.php
modified:   app/Console/Commands/Inspire.php
modified:   app/Console/Kernel.php
modified:   app/Events/Event.php
modified:   app/Exceptions/Handler.php
modified:   app/Http/Controllers/Auth/AuthController.php
modified:   app/Http/Controllers/Auth/PasswordController.php
modified:   app/Http/Controllers/Controller.php
modified:   app/Http/Controllers/HomeController.php
modified:   app/Http/Controllers/WelcomeController.php
modified:   app/Http/Kernel.php
modified:   app/Http/Middleware/Authenticate.php
modified:   app/Http/Middleware/RedirectIfAuthenticated.php

modified:   app/Services/Registrar.php
modified:   bootstrap/app.php
modified:   composer.json
modified:   config/app.php
modified:   config/auth.php

app / Console / Kernel.php中的示例命令将更改此

namespace App\Console;

protected $commands = [
    'App\Console\Commands\Inspire',
];

要

namespace todoparrot\Console;

protected $commands = [
    'todoparrot\Console\Commands\Inspire',
];

如果＆＃34; App \＆＃34;请检查文件app / Console / Kernel.php。路径仍然可用。如果可以，请转到＆＃34; todoparrot \＆＃34;。

我已经尝试运行命令＆＃34; php artisan app：name todoparrot＆＃34;。它没有任何问题。我不知道为什么它会给你的错误。

Answer 3

Ggo到C：\ wamp \ www \ laravel \在命令提示符下使用

C:\ProgramData\ComposerSetup\bin\composer dump-autoload

而不是

composer dump-autoload

当我更改命名空间时，为什么我的应用程序崩溃？
