Unable to install `google-cloud-dataflow` Python package due to missing Beam package

[tswast]

$ pip install google-cloud-dataflow
Collecting google-cloud-dataflow
  Using cached google-cloud-dataflow-2.3.0.tar.gz
Collecting apache-beam[gcp]==2.3.0 (from google-cloud-dataflow)
  Could not find a version that satisfies the requirement apache-beam[gcp]==2.3.0 (from google-cloud-dataflow) (from versions: 0.6.0, 2.0.0, 2.1.0, 2.1.1, 2.2.0)
No matching distribution found for apache-beam[gcp]==2.3.0 (from google-cloud-dataflow)

Workaround

pip install --upgrade setuptools
pip install google-cloud-dataflow==2.2.0

Note that upgrading setuptools was necessary. The Dataflow installation failed with AttributeError: '_NamespacePath' object has no attribute 'sort' before I did that. To workaround this, I had to upgrade setuptools first.

I just tried with a fresh virtualenv and it still fails.
