@alexaderramos @janakparmar9491 This package installs cleanly in fresh Laravel 8. If you've recently upgraded to Laravel 8, first remove the package using composer remove joedixon/laravel-translation, then run php artisan optimize:clear.

After this, the package installed successfully for me.

in vendor\joedixon\laravel-translation\routes Add : use Illuminate\Support\Facades\Route; then run :composer require joedixon/laravel-translation
