node-red-contrib-pixelit wont work

[hurzi008]

I installed on a new iobroker session, the node red adapter, Pixel It adapter and the node-red-contrib-pixelit.
After reboot iobroker and starting node red no new nodes for Pixel it ......

I use the script for install node-red-contrib-pixelit from npm but it seems it wont work.

Or did i make a mistake using the script??
