Build fails on MacOS Mojave

[claucece]

I tried installing jackline on macOS (Mojave, 10.14.6) by installing OCaml and following the repo instructions. This happens:

#=== ERROR while compiling jackline.0.1.0 =====================================#

Any ideas?

Thanks for your report. I added the missing dependency, could you run an opam update && opam install jackline on your computer, this should result in a successful compilation. Please comment here if it works for you or not. Thanks, and sorry for the inconvenience.

Working perfectly now! Thanks!
