Chamikara Jayalath commented on BEAM-3065: ------------------------------------------ After an offline chat with Robert, (1) This will not occur if the proto files are already there (installing a distribution from Pipy) so this should not be a blocker for 2.2.0. (2) This will not occur if grpcio-tools is manually installed before building the Beam distribution. (confirmed this). So removing this from the 2.2.0 blockers list. > Proto generation installation is broken for Windows > --------------------------------------------------- > > Key: BEAM-3065 > URL: https://issues.apache.org/jira/browse/BEAM-3065 > Project: Beam > Issue Type: Bug > Components: sdk-py-core > Reporter: Chamikara Jayalath > Assignee: Robert Bradshaw > Priority: Blocker > > "python setup.py sdist" and "python setup.py install" raises following error > for Windows.
