Resolving dependencies...
Error: cabal: Could not resolve dependencies:
[__0] trying: curryer-rpc-0.3.4 (user goal)
[__1] trying: streamly-core-0.2.1 (dependency of curryer-rpc)
[__2] next goal: streamly (dependency of curryer-rpc)
[__2] rejecting: streamly-0.10.0 (conflict: curryer-rpc => streamly==0.9.0)
[__2] rejecting: streamly-0.9.0 (conflict: streamly-core==0.2.1, streamly =>
streamly-core==0.1.0)
[__2] rejecting: streamly-0.8.3 (conflict: curryer-rpc => streamly==0.9.0)
[__2] skipping: streamly-0.8.2, streamly-0.8.1.1, streamly-0.8.1,
streamly-0.8.0, streamly-0.7.3.2, streamly-0.7.3.1, streamly-0.7.3,

streamly-0.2.0, streamly-0.1.2, streamly-0.1.1, streamly-0.1.0 (has the same
characteristics that caused the previous version to fail: excluded by
constraint '==0.9.0' from 'curryer-rpc')
[__2] fail (backjumping, conflict set: curryer-rpc, streamly, streamly-core)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, curryer-rpc, streamly,
streamly-core
Try running with --minimize-conflict-set to improve the error message.
