Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: eflint-3.1.0.2 (user goal)
[__1] trying: haskeline-0.8.2.1/installed-0.8.2.1 (dependency of eflint)
[__2] next goal: exploring-interpreters (dependency of eflint)
[__2] rejecting: exploring-interpreters-1.5.0.0,
exploring-interpreters-1.4.0.0 (conflict: haskeline =>
exceptions==0.10.7/installed-0.10.7, exploring-interpreters =>
exceptions==0.10.4)
[__2] rejecting: exploring-interpreters-1.3.0.0 (conflict: eflint =>
exploring-interpreters>=1.4.0.0)
[__2] skipping: exploring-interpreters-1.2.0.0,
exploring-interpreters-1.0.0.0, exploring-interpreters-0.4.0.0,
exploring-interpreters-0.3.2.1, exploring-interpreters-0.3.2.0,
exploring-interpreters-0.3.1.0, exploring-interpreters-0.3.0.0,
exploring-interpreters-0.2.0.0 (has the same characteristics that caused the
previous version to fail: excluded by constraint '>=1.4.0.0' from 'eflint')
[__2] fail (backjumping, conflict set: eflint, exploring-interpreters,
haskeline)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, haskeline, eflint,
exploring-interpreters
Try running with --minimize-conflict-set to improve the error message.
