Target [Laravel\Socialite\Contracts\Factory] is not instantiable
You would need to add the following in config/app.php
In providers add this
Laravel\Socialite\SocialiteServiceProvider::class
In aliases add this
'Socialite' => Laravel\Socialite\Facades\Socialite::class
What helped me is writing
use Socialite;
in the controller (just the alias, not the full path). And then running
php artisan config:clear
in the terminal.
For me, it was to add $app->register( \Laravel\Socialite\SocialiteServiceProvider::class);
to app.php
in the bootstrap folder, using Lumen 5.6
.
