php artisan serve command display error message

I am using php 7.3.2 on window 7. When I try to run php artisan serve, it shows this error on the webpage:

Whoops, looks like something went wrong.

Is it related to the message that I received when I want to migrate database, it says

Application In Production!

My error in laravel log shows

production.ERROR: RuntimeException: The only supported ciphers are AES-128-CBC and AES-256-CBC with the correct key lengths. in C:\xampp\htdocs\Inventory\vendor\laravel\framework\src\Illuminate\Encryption\Encrypter.php:43

Solution

  • Following the error in your log file you seem to be missing your key attribute in your .env file. See this SO question for a solution.

    To generate the secret key, run 

    $ php artisan key:generate

    make sure to follow the official docs when installing Laravel.
