 My advice. Delete your current MMM-WeatherBackground folder/directory. Clone the repo again 
 git clone https://github.com/cowboysdude/MMM-WeatherBackground.gitinto your modules folder.cdinto your new MMM-WeatherBackground directory. Runnpm install. You should be golden.P.S. No helper is not an error.
