Laravel 5.2 - 方法 auth 不存在

Question

我最近克隆了一个 Laravel 5.2 项目。在运行 composer install 之后，每次执行 Artisan 命令后以及尝试访问应用程序时，我都会收到以下错误：

Method auth does not exist

我可以在网上找到类似的 "method does not exist" 问题，但找不到关于 'auth' 的问题。我相信所指的 'auth' class 是内置的，可以用作各种路由的中间件。但是，我不知道如何解决这个问题。

我试过：

composer dump-autoload -o
删除供应商库并使用 composer 重新安装
正在重置到远程分支
重新克隆存储库
运行 PHP 5.6 和 7.1

如有任何帮助，我们将不胜感激！

Answer 1

将Route::auth()替换为以下路由，或者

// Authentication Routes...
    $this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
    $this->post('login', 'Auth\LoginController@login');
    $this->post('logout', 'Auth\LoginController@logout')->name('logout');

    // Registration Routes...
    $this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
    $this->post('register', 'Auth\RegisterController@register');

    // Password Reset Routes...
    $this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm');
    $this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
    $this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm');
    $this->post('password/reset', 'Auth\ResetPasswordController@reset');

Answer 2

感谢@JagadeshaNH，我得以解决问题。

routes.php 包含以下行： Route::auth();

这调用了一个生成一堆身份验证路由的函数。

在运行第一次 composer install 之后，它显然没有安装 Laravel 5.2 的所有版本更新，其中包含 php artisan make:auth 命令和实际的 auth函数。

因为这些文件不存在，所以 artisan 一直失败，应用程序不会运行。

解决方案是：

在 routes.php 文件中注释掉 Route::auth()
运行 composer update（之前因为错误没有生效）
取消注释Route::auth()

Answer 3

尝试命令

php artisan make:auth

Laravel 5.2 - 方法 auth 不存在

Laravel 5.2 - Method auth does not exist

php

authentication

laravel

composer-php
