After having to download the theme into my Magento root I run command php bin/magento setup: upgrade and I meet that error:
Magento supports 7.0.2, 7.0.4, and 7.0.6 or later. Please read http://devdocs.magento.com/guides/v2.2/install-gde/system-requirements.html
I don't understand why this error comes, maybe because my PHP version is 7.2.11..
Please help me .thanks.
