Answer 1

So this is what usually fixes it for me

1. Reinstall composer dependencies by removing vendor folder and composer.lock. Then run composer clear-cache and then composer install (this is usually the problem)

2. Check that all service providers are imported correctly in app.php under directory config

3. Make sure that your service providers are not importing something that does not exist, for example if you register a service provider in production but is only installed as dev:

   if (env('APP_DEBUG')) { $app->register(Barryvdh\Debugbar\LumenServiceProvider::class); }
