Failed to clone State_Machine during composer installation.
Running the latest version of composer from the command line but I am getting a [RuntimeException] error:
"Failed to clone https://git.drupal.org/project/state_machine, git was not found, check that it is installed and in your PATH env. sh: git: command not found."
I get a similar error previous to this for drupalcommerce/projectbase and Drupal core but it "downloads from dist" for both
Composer is latest version 1.1.3 (stable channel)
This is from a clean installation at command line as per your installation instructions.
Command: composer create-project drupalcommerce/project-base mystore --stability dev
as per link http://docs.drupalcommerce.org/v2/install.html
All help greatly appreciated.
