Mod edit (@harrisonhjones): Resolution: Use the CLI (for now) to get a full log output
In the Atom IDE I was getting this error, with no information as to the cause. I copied the relevant bits of the code to the browser based IDE and was able to identify the error when I compiled there.
It’s not going to be practical to copy back and forth like this. Can anyone tell me if there is somewhere in the Atom IDE where I can see the full build log when there is a problem like this, or is there another way to identify the problem?
