I was following DDEV installation instructions closely on macOS with Apple M2 and Orbstack as Docker provider:
composer create-project -s dev centarro/commerce-kickstart-project kickstart
cd kickstart
composer require drupal/commerce_demo:^3.0
ddev config
ddev start
But due to the error "Fatal error: Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.2.0". You are running 8.1.27. in /var/www/html/vendor/composer/platform_check.php on line 24
", I had to change config.yaml PHP version to 8.2. Then ddev start worked and the installation process completed. But when I navigate to the URL, then the site isn't reachable: No route found for "GET https://kickstart.ddev.site/" (from "https://kickstart.ddev.site/core/install.php?profile=commerce_kickstart&langcode=de"). Even the URL provided by Orbstack throws out the missing route (http://web.ddev-kickstart.orb.local/).
Help much appreciated!
Closed: works as designed
3.0
Miscellaneous
If you can't match the required PHP version in your system (I use Homebrew and will often swap the active version), you just need to append --ignore-platform-reqs to the command.
