@nightfox‍ this is an english forum, please translate it or write directly in english 😉   >   > > Hi guys, I’m a little confused. I was trying to install shopware 6 in a test server by calling ./bin/setup. The server is a shared hosting server and the default php is v7.0. \*. So I run php from version 7.2 like this /usr/local/php7.2/bin/php bin / setup I think this will start the installation of the shopware using php v7.2 But I have an error. The message is as follows Fatal Error: Uncaught TypeError: PackageVersions \ Installer :: Return Value must be an instance of PackageVersions \ void, none are returned in path / shopware6 / development / vendor / ocramius / package-versions / src / PackageVersions /Installer.php:80 I did a little google, and I got an answer like that, „The problem here is that the PackageVersions plugin is installed in the project you have currently open (or as a global dependency somewhere), and you’re trying to run it against 7.0.“ is: [Error when using Composer 1.6.4 with PHP 7.0 · Issue #64 · Ocramius/PackageVersions · GitHub](https://github.com/Ocramius/PackageVersions/issues/64) I know that shopware6 needs php v7.2 +. But why does this situation occur? I could easily install sw6 in my local system without any problem. Thank you You probably updated your repositories. Made the same mistake. run **composer update** in your development and platform repos. That should solve the requirement issue.   --- _[View the full topic](https://forum.shopware.com/t/erreur-fatale-uncaught-typeerror-valeur-de-retour-de-packageversions-installer-activate-doit/59782)._
