Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:
The openssl extension is missing, which means that secure HTTPS transfers are impossible.
If possible you should enable it or recompile php with --with-openssl
Also in that directory (for wamp systems) should be php.ini and phpForApache.ini, make sure that the openssl lines in both are uncommented. My experience suggests that the GUI only sets the 'ForApache' version, so I just use a text editor on both.
