Github version not the same as download on wordpress

[HeadwayLabs]

I cant get this version to work. I get an error when activating the plugin

Warning: require(/plugins/onepager/vendor/autoload.php): failed to open stream: No such file or directory in /plugins/onepager/tx-onepager.php on line 49

No vendor folder in this repo.

I downloaded the version on:

https://wordpress.org/plugins/tx-onepager/

This one works fine.

This is the developer version, that means you have to install the complete tool chain (node, npm, gulp and composer) and run the install command, see readme file: https://github.com/themexpert/onepager#developer

Your error message means you haven't installed composer correctly (vendor directory is missing).
