Hi,

webtest.zip This also happened to me when running a node on a Raspberry Pi 3 - Pixel. (Node.js v 4.7.0):

I discovered the reason for the issue; here is the solution:

step 1: go to the application folder, and open the given package.json file.

step 2: under the dependencies/ bundledDependenices/ developerDepende ncies, delete johnny-five from all fields within the package.json file.

step 3: run on the command line "npm install --save johnny-five", which will download the latest version of the Johnny-Five package, and the updates the johnny-five dependency to the package.json file.

step 4: run the "entry point" file of the application
