ImportError: No module named iterator for <= 0.27.0

[ensonic]

Since the modules are release without semantic versions, rebuilding my stack picked up 0.28.X and fall apart since the api changes. Before I wanted to migrate I need to get it up and running again and tried to pin to google-cloud-pubsub==0.27.0 or even google-cloud-pubsub==0.26.0 but with that I get:

Any ideas?

[ensonic]

This combination seems to work:
"google-cloud-core==0.25.0 google-cloud-logging==0.24.0 google-cloud-pubsub==0.26.0"

Any tips for how to figure out which api combination work, other than trial and error?

[dhermes]

First: apologies. We are aware of the pain that breaking google-cloud-core has caused (both for us and users) and are trying hard to get it stable. (Thanks @jonparrott!)

To give a practical answer to your question. You can actually see the dependencies on PyPI (but not on warehouse):

You can also see them in the source at the tag corresponding to the release.

Is there any ETA on fixing this? This is a major blocker for us as we have been using new pusub api everywhere and now can't use google storage. Thanks!

[dhermes]

@Marigold Can you be more specific about what you'd like to see fixed? (The output of pip freeze would be helpful.)

[Marigold]

Sorry @dhermes, I couldn't get it working on GCP yesterday, but the following req seems to be working after starting with fresh instance

google-auth==1.1.1
google-cloud-core==0.27.1
google-cloud-pubsub==0.28.3
google-cloud-storage==1.4.0
google-gax==0.15.15
google-resumable-media==0.2.3
googleapis-common-protos==1.5.3
grpc-google-iam-v1==0.11.4

thanks!

Closing as working then. :-)

Hello, I'm not sure if this is the best answer or if it would solve your problem, but some of the requirements are fairly old.
Will you be able to try the versions here?
