      Text.Megaparsec.Error (from megaparsec-9.2.0)
      Text.Megaparsec.Lexer

Thanks Gautam! would like to send a PR?

[gautam-srivastava]

@rodrigosetti - I haven't fixed the issue yet for a PR.

I can send one if I find a fix that works with my haskell environment.

Can you confirm whether you could reproduce the issue?

Still a beginner at running packages with cabal. Tried cabal install instead of cabal run.

Attaching screen shot of dependency errors, just in case anyone is still watching this repo or could set it up on their workstation.

Seems like a MacOS issue while resolving dependencies with the following set of packages.

Setup: Encountered missing dependencies:
diagrams -any,
diagrams-lib -any,
diagrams-rasterific -any,
megaparsec -any,
optparse-applicative -any,
scientific -any,
syb -any
