When trying to start profanity with the plugin loaded I get this error in my log:

Using macos 10.12.3 with profanity 0.6.0dev.master.b768c8b

ReneVolution commented 7 years ago

Did you just recently update Python?

pfannie commented 7 years ago

Same here with macOS 10.11.6 and Profanity 0.6.0dev.master.b768c8b.

I un- and reinstalled python a few times recently, so there might have been an update.

ReneVolution commented 7 years ago

@pfannie Did you restart your machine in between or at least your bash?

pfannie commented 7 years ago

@ReneVolution Yes, I did.

When I run /plugins python_version inside Profanity it shows Python 2.7.10, which is the one that originally shipped with the OS, neither Python 2.7.13 or Python 3.6.0 which I installed through homebrew. Even though python and python3 link to those respectively.

On the other hand, when trying to load the plugin, the error message says it's using the homebrew python.

By the way, I'm using iTerm2 Build 3.0.14, and zsh 5.3.1.

ReneVolution commented 7 years ago

A quick google search resulted in http://stackoverflow.com/questions/34861128/osx-using-bash-to-find-python-is-different-than-using-usr-bin-env-python.

Could you try that and report back?

pfannie commented 7 years ago

OK, so I followed python all the way back to /usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/bin/python2.7. I guess that's normal for the homebrew installation.

$ ls -l /usr/local/bin/python

These other things all result in the same output:

$ /usr/local/bin/python -c "import sys; print sys.executable; print sys.version_info"
/usr/local/opt/python/bin/python2.7
sys.version_info(major=2, minor=7, micro=13, releaselevel='final', serial=0)
$ /usr/bin/env python -c "import sys; print sys.executable; print sys.version_info"
/usr/local/opt/python/bin/python2.7
sys.version_info(major=2, minor=7, micro=13, releaselevel='final', serial=0)
$ python -c "import sys; print sys.executable; print sys.version_info"

Did you also try hash -r python as stated in the accepted answer?

pfannie commented 7 years ago

Yes. This is what hash | grep python returns:

python=/usr/local/bin/python
python-config=/usr/local/bin/python-config
python2=/usr/local/bin/python2
python2-config=/usr/local/bin/python2-config
python2.6=/usr/bin/python2.6

pythonw=/usr/local/bin/pythonw
pythonw2=/usr/local/bin/pythonw2

I also had a look at this question at SO: http://stackoverflow.com/questions/34386527/symbol-not-found-pycodecinfo-getincrementaldecoder. But for me python -c "import io" works fine, I guess, as I don't get any output.

ReneVolution commented 7 years ago

Weird ... what is the output of type python ?

pfannie commented 7 years ago

type python returns python is /usr/local/bin/python.

pfannie commented 7 years ago

I did some testing and by now I'm pretty sure that this is either an issue with homebrew or with profanity. I installed it from source and compared the config.log files with the homebrew installation and you can clearly see where the homebrew install "goes wrong":

For some reason it finds the system python stuff, which is rather strange, but doesn't have anything to do with this plugin.

ReneVolution commented 7 years ago

Fixed this in a sense that OmemoState now comes with source of this plugin.
