Should jedi-vim respect the preferred python interpreter of $PATH?

[kiryph]

I am on OSX 10.10.5 using MacVim. I have installed miniconda 2.3.0 (py27, numpy, pip installed jedi).
In my shell I have adjusted $PATH in ~/.profile, so that the default interpreter is the miniconda version

❯ which -a python
/Users/kiryph/miniconda-py2/bin/python
/usr/bin/python

I have adjusted in my vimrc also the PATH variable

let $PATH=""
            \.$HOME."/miniconda-py2/bin/:"
            \.$PATH

NOTE :!echo $PATH does not have the same order as :echo $PATH. Does anyone know why the order is changed?

Would it be sensible that jedi-vim completes according to the default python interpreter of $PATH, here the conda root environment ($ conda env list)?

Well, I don't know if sensible is the right word to use here. jedi-vim doesn't do any magic in selecting a Python interpreter at the moment. jedi-vim is just using the Python interpreter given by vim itself. So there's not really a lot to adjust there.

I have davidhalter/jedi#385 on the roadmap as a long term solution for this, but it might take a while...

Is this answer good enough?

Yes, this answer is good enough. Thanks for your explanation.

I hope that you find the time to make it possible to choose the python interpreter. There is another plugin which tries to solve it for conda envs https://github.com/cjrh/vim-conda.
And compare also https://github.com/zchee/deoplete-jedi which has a variable for the python interpreter.

I've found that I can get jedi-vim to work with my python 2.7 conda environment.

Here's what I had to do:
(1) make sure i had an up-to-date vim that was compiled with python 2.7. I used brew with the following arguments:
brew install vim --with-python@2

(2) Make sure "vi" -> "vim". (I use "vi" in the command line. If you use "vim", you should be good. I did this by adding this line to my .bash_profile.
alias vi=vim
for the longest time, vi kept crashing on me until i checked :version in vi and realized it wasn't the same version that had been brew installed.

(3) The final piece is to add the following line to my .vimrc file
let g:jedi#force_py_version=2.7
This line forces jedi to use python version 2.7. Without this line, jedi tries to use version 3.x

I hope this helps someone. I spent all day troubleshooting but fortunately, I learned a lot in the process.

@djchou Thanks for your comment. It is always good when people share their solutions.

Also keep in mind not all people respond to solutions they found and actually helped them.
