elm-reactor install failure due to elm-lang/core: "bad version bounds"

[justinmanley]

Trying to install elm-reactor from source with:

cabal sandbox init
cabal install

fails with the following error message:

Error in package elm-lang/core 1.1.0 in module Signal:

Parse error at (line 285, column 24):
unexpected "\n"
unexpected keyword 'input', variables cannot be keywords


This error is probably due to bad version bounds. You should definitely
inform the maintainer of elm-lang/core to get this fixed.

In the meantime, you can attempt to get rid of the problematic dependency by
modifying elm-stuff/exact-dependencies.json, though that is not a long term
solution.

I'm actively developing on the master branch and things are in an intermediate state. If you want to build from source, make sure you are using the latest tags on each repo.

To clarify, the compiler has some changes, so if you have literally the latest one, it won't be totally backwards compatible with everything that is online.
