toutpt / collective.etherpad Goto Github PK

I have installed Nodejs and etherpad without problems.
Then added all files form the git https://github.com/ether/etherpad-lite.git to a new plone installation. I ran the ./bin/buildout and it seems to be all right.
In mysite/plone_control_panel I also have added the product.
The problem rise when I go in the ZMI to:
//portal_registration
and I try to add collective.etherpad.layer.Layer
Here it rises the error:

Traceback (innermost last):

Hi.
I installed collective.etherpad per buildout and everything worked fine. But after activation the addon I get the following error message while trying to collaborate.

Traceback (innermost last):

I got nodejs and npm installed on a freebsd system.
