cabal: Could not resolve dependencies:

[__2] trying: shelly-1.9.0 (dependency of ihaskell)

zeromq4-haskell-0.3.1, zeromq4-haskell-0.3, zeromq4-haskell-0.2,
zeromq4-haskell-0.1 (has the same characteristics that caused the previous
version to fail: excludes 'async' version 2.2.2)
[__5] fail (backjumping, conflict set: async, ipython-kernel, zeromq4-haskell)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: async, zeromq4-haskell, ihaskell,
shelly, ipython-kernel, base, ihaskell-hvega
Try running with --minimize-conflict-set to improve the error message.
