Answer 1

Try removing the package, running php artisan optimize:clear, and installing it again. The package installs on fresh Laravel 8 project, but if you're are upgrading, I've also encountered this issue. Deleting all caches helped, the package then installed correctly.

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