Fatal Error after ant build-unit

Hi everybody, 

after i enter the “ant buid-unit” command i get this Error:

“Fatal error: Uncaught TypeError: Return value of PackageVersions\Installer::activate() must be an instance of PackageVersions\void, none returned in /home/vagra”

Could you please help me to solve this problem?

Best regards 


Hi Vanessa,

which PHP Version are you running on your system?
Did you check whether your system has all requirements to install shopware?

Kind regards,
