Elm repl seems to want some kind of setup, can't parse values #118

I just installed elm-repl for mac from the website (http://elm-lang.org/install). When I type in a simple "string", the repl fails. I feel like I'm missing something...

I ran into something unexpected when parsing your code!

I am looking for one of the following things:

    something like `exposing (..)` which replaced `where` in 0.17

I had the same problem, whatever I typed in the repl I would get this error message.

This made it work for me: I noticed that I had an elm-stuff folder and elm-package.json in my home directory which I must have accidentally created sometime (I probably missed the --global when installing). I removed that folder and elm-package and then elm-repl started working.

So I'm guessing maybe you got two versions of elm and for some reason it doesn't load all resources for repl from the same elm-installation (and probably one of them is 0.17 and the other one is not).

Yeah, sounds like you have 0.16 and 0.17 files mixed around. Solution should be to remove the relevant elm-stuff/ directory, and possibly remove the ~/.elm directory as well. Open a new issue if that does not fix it and the issue persists in 0.17.1
