After making some changes, I can no longer import Pkg.CSV

well, Julia learned from Python’s failure and has a much more robust system. Just to name a few:

  1. not setup.py bs
  2. Compatibility (both ways) is stored in the General registry, which means you don’t need to download multiple versions of the same package to “try” out the compatibility
  3. binary dependencies are managed in the exact same way as normal package
