Laravel say that Auth guard [] is not defined

Question

I'm beginer and I start learn and code with laravel... To enable user login nad registration I write this (as I see on one tutorilal) :

at routes.php

 Route::controllers([
     'auth'=>'Auth\AuthController',
     'password'=>'Auth\PasswordController', ]);

and now when I type: http://localhost:8888/auth/login I get error:

InvalidArgumentException in AuthManager.php line 71: Auth guard [] is not defined.

Also in view folder there is no auth directory and login.blade.php files and other.

Answer 1

Make sure that your config/auth.php is updated if you've upgraded from 5.1.x to 5.2.

https://github.com/laravel/laravel/blob/v5.2.0/config/auth.php

Answer 2

In case you edited your config/auth.php , eg to add another guard and your config is cached, your guards may not be reloaded. If you experience this problem, clearing the config will fix it.

$php artisan config:clear or $php artisan config:cache

I'm using laravel 5.5

Answer 3

这可能是您的 config/auth.php 文件中的一个问题，其中 'defaults' 数组在 Laravel 5.2 上设置了一个不存在的保护。

| This option controls the default authentication "guard" and password
| reset options for your application. You may change these defaults

| Of course, a great default configuration has been defined for you
| here which uses session storage and the Eloquent user provider.

| All authentication drivers have a user provider. This defines how the

| mechanisms used by this application to persist your user's data.

Answer 5

The main cause of this problem is your system can not detect newly created guard. Just run

php artisan config:clear
php artisan config:cache

If you are unable to run above artisan command or project in share hosting then write the below code to your web.php file

Route::get('/clear', function() {

    Artisan::call('cache:clear');
    Artisan::call('config:clear');
    Artisan::call('config:cache');
    Artisan::call('view:clear');
    Artisan::call('route:clear');

    return "Cleared!";

});

Now, write "clear" after your base url and hit enter.Hope your problem will solve.

Answer 6

Clear your config and cache

Php artisan config:clear

php artisan config:cache
