PHP laravel error when running any php artisan command-CodePudding

EDIT: So I am trying to use a laravel project that I already used before, whenever i use

php artisan migrate

I immediately get:

PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Class HelloVideo\Console\Kernel does not exist' in /var/www/html/orange/php/application/vendor/laravel/framework/src/Illuminate/Container/Container.php:776

And afterward, whenever I use any php artisan the same error keeps showing up..

Composer.json:

}

CodePudding user response：

Your composer.json has the following psr-4 autoloading configuration:

"psr-4": {
  "App\\": "app/"
}

However, it appears the namespace of your app is HelloVideo. Change to the following:

"psr-4": {
  "HelloVideo\\": "app/"
}

Then run composer dump-autoload.

CodePudding user response：

Do you have a app/tests/TestCase.php file on server? If not - you should remove it from composer.json (or put the file back there).
