shake: Invalid statement: import Development.Shake

Question

My first attempt using shake, tried to follow the instructions here: https://github.com/ndmitchell/shake/blob/master/docs/Manual.md#readme

I copied the makefile verbatim and ran shake. Shake printed shake: Invalid statement: import Development.Shake. My first thought was that maybe a new version had been released where these import statements had been made redundant. So I commented them out and got shake: Invalid statement: -- import Development.Shake. So I removed them. Here was the output:

shake: Error when running Shake build system:
* main
* IO
Error, file does not exist and no rule available:
  IO

GHC compiles the makefile fine. I'm not really sure what else to do to debug (I'm far from a Haskell expert!).

Somewhat relatedly (to the tutorial, at least) shake --demo no longer seems to exist.

The --demo feature will be available in the next release. I hadn't realised I'd pushed the doc updates yet, sorry about that. — Neil Mitchell, Sep 10 '14 at 11:22
@NeilMitchell, don't worry about it, it's a bit funny. Thanks for responding, in any case. — mkingston, Sep 10 '14 at 12:33

I would have preferred commenting instead of answering (I miss some reputation to do so). I apologize in advance if my "answer" is a bit off.

Have you followed the running section of the tutorial ? Or have you tried it with runHaskell ?

I would suspect something is wrong with the way you try to run the example, not the code itself.

Indeed, I've misunderstood (and not read far enough). And here I'd hoped it wasn't a silly mistake. Thank you! – mkingston Sep 09 '14 at 15:10
