Why its showing class not found errors?

I just cloned a git repo and ran the necessary commands to install the project.
When I access the login page "http://localhost:80/nova/login" it works. However after enter the correct credentials and submit it shows an error:
Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR)
Class '\App\User' not found
Do you know what can be the issue?
Also running this command:
/var/www # php artisan component:update
It shows a similar error:
Starting Update of All Component files
Symfony\Component\Debug\Exception\FatalThrowableError : Class 'App\Component' not found

After cloning, running through these steps should fix your problem:
run composer install or npm install.
check that the .env file is correct.
run php artisan key:generate
Optional: php artisan migrate
run php artisan serve

Reload composer autloaded classes.
composer dump-autoload

Symfony make:entity add property failed?

I have a problem when I want to create an entity under symfony 5.1.9 (I have the same problem under sf 4.4). I recently created a new SF project and still have the same concerns. The error message is as follows: In Validator.php line 158:
Argument 2 passed to Symfony \ Bundle \ MakerBundle \ Validator :: validateDoctrineFieldName () must be an instance of Doctrine \ Common \ Persistence \ ManagerRegistry, instance of Doctrine \ Bundle \ DoctrineBundle \ Registry given, called in D: \ phpProject \ API-bills \ vendor \ sy
mfony \ maker-bundle \ src \ Maker \ MakeEntity.php on line 303.
Thanks for help

It seems like the latest version is having some troubles. The easy fix for now is to modify your composer.json file and "downgrade" the doctrine/doctrine-bundle, from version ^2.1 to 2.1.0. After making this change, run composer update and everything should work.
As Florian said, referer to the maker bundle issues to see the complete reference on this error.

Laravel5 can't use package

I'm using L5(dev version) and trying to create package.
Doing `php artisan workbench za-web/Sidebar --resources
It's creating for me structure and service provider.
And then I'm trying to add service provider to app/config.php
'ZaWeb\Sidebar\SidebarServiceProvider'
I've got the error:
Symfony \ Component \ Debug \ Exception \ FatalErrorException (E_ERROR)
Class 'ZaWeb\Sidebar\SidebarServiceProvider' not found
Also was trying to do composer dump-autoload but it doesn't helped.

I've figured out whats wrong, theres no autoload seciton for workmench directory in bootstrap/autoload.php
I've add it and not everything ok.
if (is_dir($workbench = __DIR__.'/../workbench'))
{
Illuminate\Workbench\Starter::start($workbench);
}
