Class 'Illuminate\Cache\CacheServiceProvider' not found

I'm working on a laravel project with my Android phone.

I cleared junk files using a software and now I get error when trying to serve my project.

First I ran php artisan serve and got this error:

$ php artisan serve

In PackageManifest.php line 168:

The /storage/emulated/0/web/tbcians/bootstrap /cache directory must be present and writable .

Then I created the cache directory and ran php artisan serve again and got another error:

In ProviderRepository.php line 208:

Class 'Illuminate\Cache\CacheServiceProvider' not found

How do I fix this?
