Asset pipeline related error

I have this js file decimal.min.js which I put in the asset pipeline
javascript directory. Whether I require it in the application.js
manifest
or not, I still get the error below. This is on windows in development
mode
… Any ideas or suggestions ? I find it slightly baffling … The js file
itself does get served

maybe I should not use a minified js file in the pipeline. I switched to
a
non minified version … so far no errors but sometimes it’s been
intermittent
