The first step to install Web App Builder 2.1 is to "double-click the startup.bat" file. When I do that I get an error that says
Error: Cannot find module 'isarray'
Does anyone know what this error is or what it means? I do have node.js installed on my machine.
I am following these instructions:
Get started—Web AppBuilder for ArcGIS (Developer Edition) | ArcGIS for Developers
Thanks.
