Why get I this error "module * already defined "?

I'm trying to create a new project with this cordova library :

https://github.com/fbsanches/cordova-plugin-wallpaper

However, i get this error when i'm building the app :

Uncaught module cordova-plugin-wallpaper.wallpaper already defined

Do you have some idea ?!

I build with this command :

ionic cordova run android --device -l --debug
