-------------------------------------
Summary: Non-working Python 3 versions are installable on PyPI
Key: BEAM-4025
URL: https://issues.apache.org/jira/browse/BEAM-4025
Project: Beam
Issue Type: Bug
Components: sdk-py-core
Affects Versions: 2.2.0, 2.1.0, 2.0.0, 0.6.0
Reporter: Taylor Edmiston
Assignee: Ahmet Altay
Beam does not currently support Python 3, however, it's possible to install
_some versions_ from PyPI / Warehouse under Python 3 today. (It appears the
PyPI configuration was fixed at some point after 2.2.0.)
This affects the following 5 versions:
{code:java}
$ pip3 install apache-beam==-1
Collecting apache-beam==-1
Could not find a version that satisfies the requirement apache-beam==-1 (from
versions: 0.6.0, 2.0.0, 2.1.0, 2.1.1, 2.2.0)
No matching distribution found for apache-beam==-1{code}
This is a confusing experience for users (customers) to discover that it's
incompatible only on import after installing the package (and not reading the
docs) via the error message:
{code:java}
RuntimeError: The Apache Beam SDK for Python is supported only on Python 2.7.
It is not supported on Python [sys.version_info(major=3, minor=6, micro=4,
releaselevel='final', serial=0)].{code}
Since it's not compatible anyway, it's confusing that the non-working package
versions are installable.
I don't think there's an easy way to remove just the Python 3 build from the
wheels or in the PyPI GUI. As far as I can tell, this would require rebuilding
+ re-uploading the Python 2 wheels for affected versions.
