php - Whoops, looks like something went wrong, laravel

Solution:

First of all, inconfig/app.php set debug totrue or in your .env file setAPP_DEBUG=true. This should turn on the debugging errors On on your server. If errors are still not visible, tryphp artisan config:clear for making changes to take effect. You may also checkstorage/logs/laravel.log for errors.

Possible problems are:

• Your server's configurations does not meet the Laravel's requirements.
• Laravel does not have read/write access tobootstrap/cache folder.
• Project dependencies not installed or not supported.

Solution:

I get the solution :

• First i go to app.php and change the value of APP_DEBUG = true
• I get the error name " No application key generated "
• I run codephp artisan key:generate
