No Application Encryption Key Has Been Specified

03/27/2020 00:30:02

I'm new to Laravel and I'm trying to use the Artisan command...

php artisan serve

It displays...

Laravel development server started:

However, it won't automatically launch and when I manually enter it shows this error:

RuntimeException No application encryption key has been specified.

Any ideas? I'm using Laravel framework 5.5-dev.

From Encryption - Laravel - The PHP Framework For Web Artisans:

"Before using Laravel's encrypter, you must set a key option in your config/app.php configuration file. You should use the php artisan key:generate command to generate this key"

I found that using this complex internet query in

"laravel add encrption key" (Yes, it worked even with the typo!)

In my case, I also needed to reset the cached config files:

php artisan key:generate
php artisan config:cache

Open command prompt in the root folder of your project and run below command:

php artisan key:generate

It will generate Application Key for your application.

You can find the generated application key(APP_KEY) in .env file.
