Description
I think the minimum version for the protobuf package dependency is not correct. google-cloud-python has the version requirements as protobuf>=3.0.0, but it fails to import when using version up to and including protobuf==3.3.0. I'm not sure what the exact correct version is, but the last version of google-cloud-pubsub to work with protobuf==3.3.0 is google-cloud-pubsub==0.35.4. I believe after this commit (371333a#diff-29280288794caf553b0b008084a0e854), a protobuf version >3.3.0 is required:
Python version
$ python --version
Python 2.7.15rc1
Package versions:
$ pip list | grep -E '(cloud|protobuf)'
google-cloud-core 0.28.1
google-cloud-datastore 1.7.0
google-cloud-pubsub 0.38.0
google-cloud-storage 1.12.0
protobuf 3.3.0
Getting a stack track just importing pubsub (in ipython here)
