Some ideas:
* What does this output: `which ghc ; stack exec which ghc`
* What does your stack.yaml look like?
* Do you have a .ghci or other kinds of local configuration file?

For this file I don’t have any stack.yaml. I just wrote the file and tried to
load it into ghci.

As far as I can tell, no.

I'm not sure how it happened, but it looks like you ended up with some
files in ~/.stack which are linked against a system-wide GHC. In particular:
Library not loaded: /usr/local/opt/ghc/lib/ghc-8.0.2/transformers-0.5.2.0/
libHStransformers-0.5.2.0-ghc8.0.2.dylib
The easiest way to fix this is to just wipe out your ~/.stack directory,
which will result in having to do some recompiles, but otherwise should be
harmless.
