A common issue you might experience when working on a Laravel application is the exception:

RuntimeException No application encryption key has been specified.

You'll often run into this when you pull down an existing Laravel application, where you copy the .env.example file to .env but don't set a value for the APP_KEY variable.

At the command line, issue the following Artisan command to generate a key:

php artisan key:generate

This will generate a random key for APP_KEY, After completion of .env edit please enter this command in your terminal for clear cache:php artisan config:cache

Also, If you are using the PHP's default web server (eg. php artisan serve) you need to restart the server changing your .env file values. now you will not get to see this error message.

I ran into this issue when I manually copied the contents of my Laravel project  say sites oldname  into a new directory on my Mac  say  sites newname    Since I was manually dragging and droppping  it didn t grab the hidden files  namely    env   When I looked more closely at sites oldname I saw  editorconfig   env   env example   gitatrributes   styleci yml  etc   The error went away once I copied the hidden files to the new directory   So   No Application Encryption Key Has Been Specified  is Laravel speak for  your  env file is missing

Okay  I ll write another instruction  because didn t find the clear answer here  So if you faced such problems  follow this    Rename or copy rename  env example file in the root of your project to  env        You should not just create empty  env file  but fill it with   content of  env example     In the terminal go to the project root directory not public folder  and run       php artisan key generate    If everything is okay  the response in the terminal should look like this      Application key  base64 wbvPP9pBOwifnwu84BeKAVzmwM4TLvcVFowLcPAi6nA     set successfully     Now just copy key itself and paste it in your  env file as the value to APP KEY  Result line should look like this       APP KEY base64 wbvPP9pBOwifnwu84BeKAVzmwM4TLvcVFowLcPAi6nA     In terminal run      php artisan config cache   That s it

I found that most answers are incomplete here  In case anyone else is still looking for this   Check if you have APP KEY  in your  env  if not just add it without a value  Run this command  php artisan key generate  This will fill in the value to the APP KEY in your  env file  Finally  run php artisan config cache in order to clear your config cache and recache your config with the new APP KEY value
