Installation issue

Hi everyone. I need some help.

PHP Fatal error: require_once(): Failed opening required ‘…/vendor/autoload.php’ (include_path=’.:/usr/share/pear:/usr/share/php’) in …/bin/grav on line 18

I’m using VestaCp .

Did you install the zip from the downloads page? It has everything you need including vendor libs. The GitHub version doesn’t include vendor libs by default , they have to be installed with composer.
