@Casyfill Thanks for opening this issue!

This must be because of enum34 being installed in Python3.6 which includes enum as a standard package. This dependency should be conditionally included which was fixed in one of the dependencies of halo but not released.

I've made a release today v0.0.25 which should fix this issue. Kindly check and let me know if you're still facing it.

@Casyfill Closing this as it should be fixed.

Please let me know if it still persists.
