Jedi-vim not working, thinks Jedi is not installed

Issue

Hi there, I’ve tried for a while to get this working and have gone through a number of solutions that I have found that have worked for others. However, whenever I try and run vim with jedi-vim installed I get:

Please install Jedi if you want to use jedi-vim. The error was: /home/USER/anaconda3/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _Py_write_noraise Please install Jedi if you want to use jedi-vim. The error was: /home/USER/anaconda3/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _Py_write_noraise

Steps to reproduce

Open a .py file with vim

So, I might be completely off with my reasoning, but, for some reason, the lib-dynload cpython packages are not working properly with the latest anaconda python version.

If you set your PYTHONPATH to use the system version (I’m using manjaro btw) , jedi-vim works perfectly.

This is the way I set up the PYTHONPATH variable in my machine now.

export PYTHONPATH=$PYTHONPATH:/usr/lib/python37.zip:/usr/lib/python3.7:/usr/lib/python3.7/lib-dynload:/usr/lib/python3.7/site-packages

Hopefully there won’t be a lot of problems in terms of my development workflow.

I’m pretty sure the problem is a broken Python/VIM installation. No idea how to solve it (downgrade/upgrade?). As long as :py3 import subprocess it’s definitely not a jedi/jedi-vim issue!
