--------------------------------
Summary: Detect suitable Python & pip executables in Python-SDK
Key: BEAM-1693
URL: https://issues.apache.org/jira/browse/BEAM-1693
Project: Beam
Issue Type: Bug
Components: sdk-py
Reporter: Tibor Kiss
Assignee: Tibor Kiss
Python SDK currently supports Python-2.7 only.
The Python interpreter & pip definition in pom.xml points to {{python2}} &
{{pip2}} respectively.
Users with multiple Python interpreters installed might end up having python2
and pip2 pointing to their 2.6 installation. (This scenario happens mostly on
OS X machines.)
There is no single, valid name for the executables as different OSes install
those binaries in various names:
- CentOS6/EPEL: pip (python 2.6) & pip2 (python 2.6) & pip2.6 (python 2.6)
- CentOS7/EPEL: pip (python 2.7) & pip2 (python 2.7) & pip2.7 (python 2.7)
- Debian7: pip (python 2.7) & pip-2.6 (python 2.6) & pip-2.7 (python 2.7)
- Debian8: pip (python 2.7) & pip2 (python 2.7)
- Debian9: pip (python 2.7) & pip2 (python 2.7)
- Ubuntu1204: pip (python 2.7)
- Ubuntu1404: pip2 (python 2.7)
- Ubuntu1604: pip (python 2.7) & pip2 (python 2.7)
- OS X: pip (python 2.6) & pip2 (python 2.6) & pip2.7 (brew / python 2.7)
- Windows: pip-2.7 (python.org based installer)
To overcome this problem the pom.xml should be extended to determine the
suitable Python interpreter & pip automatically, in a platform independent way.
