Install error on macOS

[Stanzilla]

I know macOS is not officially supported but I tried and this error was a bit confusing for me

ERROR: Cannot install ilua==0.1.0, ilua==0.2.0 and ilua==0.2.1 because these package versions have conflicting dependencies.

The conflict is caused by:
    ilua 0.2.1 depends on twisted
    ilua 0.2.0 depends on twisted
    ilua 0.1.0 depends on twisted

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies

Any ideas what could cause this?

That is indeed confusing :O why the hell did it start downloading every version ever published.

I'd try:

1. force specific version (ilua==0.2.1)
2. update pip, something is seriously wrong lol.

[Stanzilla]

So I guess the problem is Twisted?

[guysv]

maybe try installing twisted first? any version will do.

[Stanzilla]

I did, might just be the end of the road already?
