Powerline: Problem with ipython3

[qoheniac]

  File "/usr/lib/python3.6/site-packages/powerline/bindings/ipython/since_5.py", line 11, in <module>
    from powerline.bindings.ipython.post_0_11 import PowerlineMagics, ShutdownHook
ModuleNotFoundError: No module named 'powerline.bindings.ipython.post_0_11'

EDIT: Replaced single backticks with 4-space indent.

What iPython version? And do not use single backticks for code blocks, there are lots of alternatives which do keep newlines: <pre>, triple backticks (on their own lines), 4-space indent.

[qoheniac]

IPython 5.3.0 with Python 3.6.2 gives the error while IPython 5.3.0 with Python 2.7.13 works.

EDIT:

$ ls /usr/lib/python3.6/site-packages/powerline/bindings/ipython
__init__.py  __pycache__  since_5.py

$ ls /usr/lib/python2.7/site-packages/powerline/bindings/ipython
__init__.py  __init__.pyc  post_0_11.py  post_0_11.pyc  pre_0_11.py  pre_0_11.pyc  since_5.py  since_5.pyc

@qoheniac It looks like you have broken installation, you need to reinstall powerline: setup.py does not alter installed file sets depending on Python version.

[aairey]

I am having the same issue on Fedora 26.
Using powerline from the official repositories.

Tried a sudo dnf reinstall powerline to no avail.
powerline works perfectly with zsh, vim, tmux just not with ipython/ipython3.

@aairey This needs to be directed by package maintainer, I do not know why dnf is not installing files which are present in the repository (and what is “dnf” in first place except that this should be some fedora package manager based on your comment). In this issue tracker only pip package is maintained.

[aairey]

Thanks Nikolai, will contact the maintainer.

FWIW: DNF is YUM's successor.

[qoheniac]

@aairey Did you hear anything from the maintainer yet?

[nikaro]

For those using Fedora and powerline from the repositories. I don't know why but Fedora package maintainer move post_0_11.py somewhere else: https://src.fedoraproject.org/rpms/powerline/blob/master/f/powerline.spec#_147

You can fix it with this workaround:

sudo ln -s /usr/share/powerline/ipython/*.py /usr/lib/python3.6/site-packages/powerline/bindings/ipython/

[aairey]

We should create a bug report for this with Fedora, but was not able to yet.

[nikaro]

Done here: https://bugzilla.redhat.com/show_bug.cgi?id=1554741

Testing working for me, please test and report back if you can

[nikaro]

Tested on F27 and it works, thank you :-)

I have reported it here https://bodhi.fedoraproject.org/updates/FEDORA-2018-d6a558d13b should i do something else?
