So, to preface, I'm a complete novice when it comes to web development. I've never done it before, but my boss wants an e-commerce site built in Drupal 8. So, I'm following the steps listed in the Drupal Commerce 2.x installation. Composer needs a little finagling to get working, but I manage it.
I run the "composer create-project drupalcommerce/project-base mystore --stability dev" string, then attempt to import the site in Acquia Dev Desktop 2. The result: "Does not appear to be a valid Drupal root folder. There must be one or more folders in 'sites' containing settings.php." I've tried copying the settings.php file from a known good Drupal 8 testSite I've built, but all that does is uninstall Commerce 2.x when I load the site.
How do I fix this?
