Red Hat Bugzilla – Bug 1269952
python scripts using #!/usr/bin/env python shebang will be affected by python3 default interpreter in Fedora 23.
Last modified: 2016-02-01 03:46:27 EST
Description of problem:
Python scripts have #!/usr/bin/env python will fail to execute in Fedora 23
Version-Release number of selected component (if applicable):
Run /usr/bin/env python in terminal
Steps to Reproduce:
python file not found.
The script should run irrespective of python3 being the default interpreter
This would affect the software supporting both py2.X and py3.X versions.
Can somebody update what is the resolution for this bug ?
Will there be python file soft linked to python3 ?
The current upstream recommendation is that "python" should mean Python 2 (see [PEP 394]). As with any script, you need to install the interpreter that can run it – in this case, Python 2.
Alternatively, you can change the shebang to "#!/usr/bin/env python3".
A shebang that would somehow automatically choose between py2 and py3 is being discussed upstream: https://mail.python.org/pipermail/linux-sig/2015-October/000000.html
[PEP 394]: https://www.python.org/dev/peps/pep-0394/
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Did that answer your question, or do you need any more info?
Yes Petr that answered my question. Sorry for delay in my response.
We updated the code with "#!/usr/bin/env python3" shebang
Thanks for the reply. I'll close the bug, but get in touch if anything else is unclear.
