For the record:

enum on PyPI -- preexisting third-party enum library

enum34 on PyPI -- backport of the 3.4 stdlib enum

aenum on PyPI -- advanced enum library compatible with the stdlib version, and maintained by the same fellow (me)

enum in the stdlib -- this was added in version 3.4 and has been a part of Python ever since.

Sadly, I don't know how to solve your problem.
I tried running PyInstaller to create a simple executable, but it generated errors which other posts here suggest its an enum vs enum34 issue. I am running Python 3.7 and for some odd reason my installation has only enum34 (1.1.6).
I am NOT an IT guy, but I am the sole programmer for a startup and am terrified of breaking my environment and not being able to fix it.
Is the proper procedure to simply install enum (I understand it may overwrite enum34), or uninstall enum34, then install enum?
I've also seen posts where folks had difficulties deleting enum34. Any hints on how to avoid those?
