Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: shake-bench-0.1.0.2 (user goal)
[__1] trying: diagrams-core-1.5.0 (dependency of shake-bench)
[__2] trying: base-4.14.1.0/installed-4.14.1.0 (dependency of shake-bench)
[__3] next goal: Chart-diagrams (dependency of shake-bench)
[__3] rejecting: Chart-diagrams-1.9.3 (conflict: diagrams-core==1.5.0,
Chart-diagrams => diagrams-core>=1.3 && <1.5)
[__3] skipping: Chart-diagrams-1.9.2, Chart-diagrams-1.9.1,
Chart-diagrams-1.9, Chart-diagrams-1.8.3, Chart-diagrams-1.8.2,
Chart-diagrams-1.8.1, Chart-diagrams-1.8, Chart-diagrams-1.7.1,

Chart-diagrams-1.2.2, Chart-diagrams-1.2, Chart-diagrams-1.1,
Chart-diagrams-1.0 (has the same characteristics that caused the previous
version to fail: excludes 'diagrams-core' version 1.5.0)
[__3] fail (backjumping, conflict set: Chart-diagrams, diagrams-core,
shake-bench)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, diagrams-core, Chart-diagrams,
shake-bench
Try running with --minimize-conflict-set to improve the error message.
