I'm trying to install the community edition by composer 2.1.2 but the logs show that I have the php8 installed and that I must use the php7. I have already installed the php7 but still requiring the right version. So please can anyone help.
composer create-project --repository-url=https://repo.magento.com/ magento/project-community-edition=2.4.0 /home/magento/
Your requirements could not be resolved to an installable set of packages.
- Root composer.json requires magento/product-community-edition 2.4.0 -> satisfiable by magento/product-community-edition[2.4.0].
- magento/product-community-edition 2.4.0 requires php ~7.3.0||~7.4.0 -> your php version (8.0.7) does not satisfy that requirement.**
