Laravel error: PHP Fatal error: Uncaught ReflectionException: Class config does not exist in Container.php:738

Practice



When starting a Laravel application

error

PHP Fatal error: Uncaught ReflectionException: Class config does not exist in /home/vagrant/engltr/vendor/laravel/framework/src/Illuminate/Container/Container.php:738
Stack trace:
#0 /home/vagrant/engltr/vendor/laravel/framework/src/Illuminate/Container/Container.php(738): ReflectionClass->__construct('config')

possible causes

1) remove this code from bootstrap/app.php :

$app->register(\Barryvdh\DomPDF\ServiceProvider::class);

and
$app->configure('dompdf');

2) one of the providers being used is not enabled

/config/app.php add the provider


3) try reconfiguring or clearing the caches


php composer.phar dump-autoload

clearing caches

php artisan config: cache 

php artisan cache: clear


4) check the write permissions of the /bootstrap/cache/ folder (777 or 775 or 755)

sudo chmod 775 storage -R

sudo chmod 775 vendor -R

sudo chmod 775 bootstrap -R

5) check the APP_NAME setting in your .ENV file for any value that has spaces in it; if it does, wrap it in quotes
