I'm not getting firmware file

When I verify the code on my spark dev, I don’t get a firmware file and when I try to open the serial monitor I get the error “Uncaught error: Invalid port specified: undefined”. What is wrong with my IDE?

Did you get a compile error?

I have to ask: have you tried restarting it (the IDE), and maybe your computer? Also, what OS are you on?

@Moors7; I haven’t tried restarting the computer, but I did restart the IDE, and I’m using windows 8.1
@kennethlimcp: I didn’t get a compile error, in fact it doesn’t respond until I open the serial monitor.
