cakephp 3 installation error with composer

Question

I have Php 7 installed but whenever I try to install CakePHP from the command line using composer I get this error:

Your version of PHP, 5.4.0beta2-dev, is affected by CVE-2013-6420 and cannot safely perform certificate validation, we strongly suggest you upgrade.

my PHP version is up to date and I can't install CakePHP locally as it will provide many errors

Answer 1

Just read that error message again. It's more than clear:

Your version of PHP, 5.4.0beta2-dev, is affected by CVE-2013-6420 and cannot safely perform certificate validation, we strongly suggest you upgrade.

You obviously don't run php 7 in your CLI environment.
