Python 3 support?
sloria opened this issue · 8 comments
I've compiled vim with python3 support, and I get the following error when opening a javascript file:
tern requires python support
tern requires python support
Error detected while processing /Users/sloria/.vim/bundle/tern_for_vim/after/ftplugin/javascript_tern.vim:
This is because the plugin is checking for has('python') but not for has('python3'). Does tern_for_vim support python 3?
I believe the Python code was initially written with Python 3 compatibility in mind. Could you try removing the check (or making it also pass when python3 is present), and tell me if you run into any problems?
I changed the following in autoload/tern.vim:
if !has('python') && !has('python3')
echo 'tern requires python support'
finish
endifto make the script execute.
However, when I open a JS file, I get the following error:
Error detected while processing /Users/sloria/.vim/plugged/tern_for_vim/autoload/tern.vim:
line 8:
E319: Sorry, the command is not available in this version: pyfile /Users/sloria/.vim/plugged/tern_for
_vim/script/tern.py
Try changing pyfile to py3file...
After changing to py3file, I get a number of Python 3-related errors (e.g. usage of urllib2) in tern.py.
I can work on a PR for Py2/3 compatibility this evening.
The tern_for_sublime plugin has Python code that is known to run both in Python 2 and Python 3, you might want to steal some code from there.
I am still seeing this on Mac OSX after installing this plugin:

Python 2.7.5 is available in my path, not sure why this issue would occur. I installed python3 via homebrew to ensure I have python3 in my path, and still, same error
Looks like my vim is compiled w/out python support, probably this is the reason:

Indeed, that's the problem.
