composer – create-project Fails With 404 Error at Repository

I am using a brand new installation of Acquia Dev Desktop on Windows 10. When I try to use composer to create a new project I get the followin output using the -vvv option:

composer create-project drupal/drupal-project:8.x hhc –no-interaction –no-install -vvv

Writing C:/Users/JimD/AppData/Local/Composer/repo/https— into cache

Could not find package drupal/recommended-project with version 8.x.

This happens with both composer versions 1.10 and 2.0.7.
I have tried all of the following and got the same result after each.

composer clear-cache
upgrade from version 1.10.13 to 2.0.7
clear-cache and composer reloaded all the .json files from repository in to cache.
Uninstalled Acquia and removed all file folders related to composer.
Tried different –stability options
Tried installing project for other platform

composer create-project -n concrete5/composer dreamrs –no-install -vvv

Tried repositories and

In every case I get the “Could not find package” error.

Latest effort, I downloaded the recommended-project.json file, put it in an empty folder and ran ‘composer install -vvv’. I got a 404 error for every package. Here are some examples:



Any idea what is going on here? I can download other packges such as hirak/prestissimo and grasmash/composerize-drupal.
