But then I try to evaluate `1 + 1`, and it says \"Unable to find a set of packages that will work with your constraints.\" Screenshot: http://imgur.com/PoWBXwS\r\n\r\nI don't recall it failing so quickly with the previous version I had tried out (0.14.0?), and I've since then installed some portion of cabal and stack — might there be some conflict there?\r\n\r\nOr is there a way to get to get Elm to tell me little bit more about the set of packages that _will_ work with the constraints of basic arithmetic?\r\n\r\n\r\n"}}
