Resolving dependencies...
cabal: Could not resolve dependencies:
trying: JuicyPixels-3.2.9.1/installed-HWw... (user goal)
next goal: debug-tracy (user goal)
rejecting: debug-tracy-0.1.0.0 (conflict: JuicyPixels =>
base==4.10.1.0/installed-4.1..., debug-tracy => base>=4.9 && <4.10)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, JuicyPixels, debug-tracy
Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.
