[Haskell-beginners] Using "cabal test" and getting "cabal: Prelude.read: no parse"

[Daniel King]

Hi all,

I created a cabal project with the attached cabal file. I run:

  cabal configure --enable-tests
  cabal build
  cabal test

and then I get the error:

  cabal: Prelude.read: no parse

I'm not sure how to debug this any further. If I execute:

  ./dist/build/scientific-pl-testsStub/scientific-pl-testsStub

with any input I've tried (numbers, array notation, string notation,
etc.) and I get that same error.

I can post the whole project if that is helpful.

Thanks for the debugging tips!

The full log is:
