After running the composer command:

composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition magento2

I am receiving the following error: An error has happened during application run. See exception log for details.

and in the logs:

main.CRITICAL: No key available {"exception":"[object] (RuntimeException(code: 0): No key available at Development/magento2/vendor/magento/framework/Encryption/Encryptor.php:255)"} []

Not sure why I am not getting the setup wizard. I saw the same issue here. Can you share your thoughts why I am receiving that error ? Thank you

try to install it manually without composer and see if it works may be its because magento does not support windows os

  • ohh, I m using Ubuntu 20 with Valet/Linux btw Commented Aug 2, 2020 at 15:10
  • I downloaded the archive, but i m still facing the same issue :( Commented Aug 3, 2020 at 18:11

You have to install magento via command line with:

php bin/magento setup:install
