I am trying to install Drupal 8 on Windows using composer and drupal-project. It is failing on the first package install; cweagans. I have rebooted the box and checked all the permissions. Composer is creating the drupal-project folder and I see D:\Websites\drupal-project\vendor\cweagans\ is there. I have attached a screen shot of the command window with the command and error messages. Does anyone know of a work-around or another method to install drupal with composer?
