I have a problem. I am download project from hosting. now when I run the project this error shows. pic attached. I think this is cache problem, I clear cache, view, but still same issue.

CodePudding user response：

let's say you have installed composer,

now run this command and see:

composer dump-autoload

CodePudding user response：

Just delete the vendor directory and composer.cache file from project root and hit the following commands.

composer install
php artisan optimize:clear
php artisan serve

Through these, you can also check if there is any composer-related issue.
