Resolving dependencies...
cabal: Could not resolve dependencies:

[__7] skipping: base-4.14.1.0, base-4.14.0.0 (has the same characteristics
that caused the previous version to fail: excluded by constraint '>=4.5 &&
<4.14' from 'svg-builder')

[__7] fail (backjumping, conflict set: base, fei-datasets, svg-builder)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, Chart-diagrams, hip,
svg-builder, vector, hip:disable-chart, primitive, lucid-svg, fei-datasets
Try running with --minimize-conflict-set to improve the error message.
