Laravel Class Socialite not found
(9 answers)
Closed 5 years ago.
I am using Socialite package in my app. I followed all the instructions from the official github page. I am using Laravel 5.4.27. When I try to run the app, I get "Class 'Socialite' not found"error. What do I need to do??
I have also added use Socialite;, Laravel\Socialite\SocialiteServiceProvider::class, and 'Socialite' => Laravel\Socialite\Facades\Socialite::class, and I am using version 3 of socialite.
Here's the controller:
<?php
namespace App\Http\Controllers\Auth;
use Socialite;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class SocialLoginController extends Controller {
public function redirectToProvider($service, Request $request) {
return Socialite::driver($service)->redirect();
}
public function handleProviderCallback($service, Request $request) {
}
}
What do I do?

Answer 1

Try composer dump-autoload
composer install installs the vendor packages according to composer.lock (or creates composer.lock if not present),
composer update always regenerates composer.lock and installs the lastest versions of available packages based on composer.json
composer dump-autoload won’t download a thing. It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php). Ideal for when you have a new class inside your project.
Ideally, you execute composer dump-autoload -o , for a faster load of your webpages. The only reason it is not default, is because it takes a bit longer to generate (but is only slightly noticable)
EDIT:
Also clear the config cache:
php artisan config:clear
