ContextualVersionConflict grpcio dependency conflict

[lbenc135]

BUG REPORT

ORIGINAL ISSUE: apache/pulsar#7477

Describe the bug

When installing pulsar-client==2.6.0 there's a dependency conflict with grpcio library.

In apache-bookkeeper-client==4.11.0 the dependency grpcio<1.26.0 was introduced, but pulsar-client installs the latest version.

The dependency tree is (as I understand it):

• pulsar-client (2.6.0)
  • grpcio (any)
  • apache-bookkeeper-client (4.11.0)
    • grpcio >=1.8.2,<1.26.0

To Reproduce

Steps to reproduce the behavior:

1. pip install pulsar-client==2.6.0
2. grpcio==1.30.0 gets installed
3. If I try to build my own pip package with pulsar-client as dependency, and try to build it, I get the ContextualVersionConflict error

Expected behavior

I expect the correct version to be installed and/or the dependency tree to be fixed.

+1 for this issue. Can the dependency be relaxed for bookkeeper Python client to be grpcio (any)?

[ca-simone-chiorazzo]

Is there any update on this? Due to the fact that bookkeeper requires grpcio==1.25.0, we are not able to install grpcio on a max os x environment with python3.8 because no wheel has been published.

Is there a plan to relax this dependency?
