Sorry in advance if this is the wrong place to put this, but I'm experiencing problems with the web app builder and I'm not sure where else to post. I've been following the instructions: node js is already on my computer, I downloaded the files, and I have not touched anything. However, attempting to run server.js in node gives this error:
Error: Tried loading "jimu/shared/basePortalUrlUtils" at ../client/stemapp/jimu.js/shared/basePortalUrlUtils.js then tried node's require("jimu/shared/basePortalUrlUtils") and it failed with error: Error: Cannot find module 'jimu/shared/basePortalUrlUtils'
I went to the directory in question and the file is there. Thanks for any help.
