Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] next goal: freckle-app (user goal)
[__0] rejecting: freckle-app-1.0.2.6 (constraint from user target requires
==1.0.2.5)
[__0] trying: freckle-app-1.0.2.5
[__1] trying: template-haskell-2.16.0.0/installed-2.16.0.0 (dependency of
freckle-app)
[__2] trying: hspec-core-2.9.4 (dependency of freckle-app)
[__3] next goal: ghc (dependency of hspec-core)
[__3] rejecting: ghc-8.10.2/installed-8.10.2 (conflict: freckle-app =>
containers>=0.6.5.1, ghc => containers==0.6.2.1/installed-0.6.2.1)
[__3] rejecting: ghc-9.2.1 (conflict:
template-haskell==2.16.0.0/installed-2.16.0.0, ghc =>
template-haskell==2.18.*)
[__3] skipping: ghc-9.0.2 (has the same characteristics that caused the
previous version to fail: excludes 'template-haskell' version 2.16.0.0)
[__3] trying: ghc-8.10.2
[__4] rejecting: ghc:-buildable (conflict: template-haskell =>
base==4.14.1.0/installed-4.14.1.0, ghc -buildable => base<0)
[__4] rejecting: ghc:+buildable (manual flag can only be changed explicitly)
[__4] fail (backjumping, conflict set: ghc, template-haskell, ghc:buildable)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: freckle-app, hspec-core, base,
template-haskell, ghc, ghc:buildable
Try running with --minimize-conflict-set to improve the error message.
