can you please point me who is load enum-compat?

I didn't find any reference to enum-compat in the project
so I don't understand which module should have the dependency

and also from description of enum-compat
```enum-compat
===========

This is a virtual package, its whole purpose is to install enum34 on
Python older than 3.4. On Python 3.4+ it's a no-op.```
also this package doesn't have any installed files

@Sudhee,

When I moved this bug to incomplete state - I didn't find which package should have additional dependency.
I awaited that Yuvaraja will answer to me and move the bug into new state.

Then bug was moved to Lukasz cause he started review before me. He was informed about this bug in the review.

@vimal, is it a RHOSP setup?

Revision history for this message
Andrey Pavlov (apavlov-e) wrote :

eventlet of version 0.20.x and 0.21.x requires enum-compat in setup.py.
enum-compat is not available in RedHat repos and in openstack-ocata repos (CentOS)

there are two solutions:

1) patch eventlet of used version 0.20.1 and store it into our tpc repo (remove enum-compat from setup.py or change it to enum34 that is present as a package and present in teh system)

2) use eventlet of version 0.18.2 that works well in Ocata

similar issue https://bugzilla.redhat.com/show_bug.cgi?id=1432165
so another solution is to ask RedHat to rebuild eventlet without enum-compat in its setup.py
