Error No Application Encryption Key Has Been Specified

Question

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

php artisan serve

It displays:

Laravel development server started: http://127.0.0.1:8000

However, it won't automatically launch and when I manually enter http://127.0.0.1:8000 it shows this error:

RuntimeException No application encryption key has been specified.

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

Hello @kartik,

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.

Hope it helps!!
Thank you!!
