I'm experiencing a similar issue.

it seems that ZEO = 5.1.1 version pin is giving me problems.

Relstorage < 2.0.0 gives an errror on startup:

  File "/home/flip/plone5/rfasite/eggs/RelStorage-1.6.3-py2.7.egg/relstorage/options.py", line 22, in <module>
    from ZEO.zrpc.connection import Connection as __Connection
ImportError: No module named zrpc.connection

Relstorage 2.1.0 doesn't build:

  [versions] constraint on zeo: 5.1.1
  Requirement of relstorage: ZEO<5.0,>=4.3.1
While:
  Updating instance.
Error: The requirement ('ZEO<5.0,>=4.3.1') is not allowed by your [versions] constraint (5.1.1)

I have a 5.1rc2 site running with relstorage = 2.1a2 and ZODB = 5.1.1 pinned

I'm able to run buildout, but I haven't actually tested relstorage yet

cdw9 · February 22, 2018, 6:40pm

oh, and relstorage 2.1.0 is out now

flipmcf · February 22, 2018, 6:42pm

I've been using 2.1.0

For lol's, I'm building with 2.1a2 now to see what's up.

ZEO 5.1.1 ZODB was a typo yes?

Ah! I think it's my python version:

github.com

zodb/relstorage/blob/5ab2840552066d0cca4db85ac8b51041ef778357/setup.py#L140


    ],
    ":python_full_version == '3.6.0rc1' or python_full_version == '3.6.2rc1'": [
        # For some reason ZEO isn't getting installed
        # on 3.6rc1/pip 9.0.1/tox 2.5.1, or 3.6.2rc1. Looks like the
        # version selection <, >= environment markers aren't working.
        # So we give a full version spec, which seems to work.
        # We see this on Travis especially.
        'ZODB >= 4.4.3',
        'ZEO >= 4.3.1',
    ],
    ":python_full_version < '2.7.9'": [
        # We must pin old versions prior to 2.7.9 because ZEO
        # 5 only runs on versions with good SSL support.
        'ZODB >= 4.4.3, <5.0',
        'ZEO >= 4.3.1, <5.0'
    ],
    'test': tests_require,
},
entry_points={
    'console_scripts': [
        'zodbconvert = relstorage.zodbconvert:main',

And my error is:

Error: The requirement ('ZEO<5.0,>=4.3.1') is not allowed by your [versions] constraint (5.1.1)

I'm going to pull on this thread and see what happens.

With a python 2.7.13 I have a different error.

But can confirm that relstorage doesn't complain. ¯\_(ツ)_/¯
