Jedi-vim: Jedi-vim not working, thinks Jedi is not installed

[mattrbrousseau]

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

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

Problem is this: The error was: /home/mattrbrousseau/anaconda3/lib/python3.6/lib-dynload/_posixsubprocess.cpython-36m-x86_64-linux-gnu.so: undefined symbol: _Py_write_noraise

No idea where that comes from. Maybe an anaconda issue?

Does python3.6 -c 'import jedi' work on your system?

[mattrbrousseau]

It does work, yes...

I was wondering if it were an anaconda issue but I'm not sure why that's happening

[davidhalter]

Can you do something like jedi.Script('str').goto_definitions()? Does that also work?

[mattrbrousseau]

So I started Python, imported jedi, ran that line and got:

[<Definition class str>]

[davidhalter]

I'm pretty sure that this is an issue that we were already having and related to environments. We're trying to fix it in https://github.com/davidhalter/jedi/pull/1108 and https://github.com/davidhalter/jedi/pull/1124. Just give us some time.

[blueyed]

1. Does :py3 print(1) work in Vim?
2. If so, does :py3 import jedi work? (it likely won't work I guess, since that is what :JediDebugInfo does basically.)

If 1. fails already then there is an issue with your Vim's Python 3.
If so, does :py print(1) work?

[mattrbrousseau]

:py3 print(1) prints 1 as it should. I receive the same error from :py3 import jedi however.

[mattrbrousseau]

[davidhalter]

Does :py3 import subprocess work in Vim?

[mattrbrousseau]

That does not work, no. I get the same _Py_write_noraise error.

[davidhalter]

What is python3.6 -c 'import sys; print(sys.executable)'?

It clearly feels like something in your Python environment is broken. This is definitely not a jedi issue if you cannot load subprocess. I'll close the ticket, because it's not an issue on our side, but I'll happily keep assisting you in finding a solution. Please just keep writing.

[mattrbrousseau]

I really appreciate this, thank you.

When I enter the command I get: /home/mattrbrousseau/anaconda3/bin/python3.6

[davidhalter]

And in that environment you can import subprocess? It's strange that it's not working in VIM.

[mattrbrousseau]

I can, yes. It's incredibly bizarre as it's the only python environment I have installed and I have no issues with anything except for Jedi...

[davidhalter]

Well, most VIM plugins don't really use a lot of Python, so I think that's very understandable. Still it feels kind of strange that this happens.

If I were you I would try to reinstall both anaconda and VIM. Maybe anaconda plays bad with VIM in general and you should be using the "official" Python? Then again, this doesn't make a lot of sense, because they are pretty much the same AFAIK.

[blueyed]

@mattrbrousseau
Could you figure it out?
If not, please try https://github.com/davidhalter/jedi/pull/1124, i.e. use the PR's branch in pythonx/jedi.

[DoktorMike]

I have the same issue in my installation.

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

However when I run

pip install jedi

All is fine:

Requirement already satisfied: jedi in /home/michael/anaconda3/lib/python3.6/site-packages
Requirement already satisfied: parso==0.1.* in /home/michael/anaconda3/lib/python3.6/site-packages (from jedi)

Any ideas?

[davidhalter]

You seem to be having this issue: https://github.com/davidhalter/jedi-vim/issues/823#issuecomment-391168599

We're still working to improve some things about environments, but I think your Python installation is just somehow broken. If this is not possible:

Does :py3 import subprocess work in Vim?

You're essentially screwed, because that's standard library stuff that is not working.

[lawly]

I have the same issue.

What I've noticed, we both use some kind of the same environment: anaconda3/miniconda3. Is there some kind of missing library I have to install to this environment to get it working?

EDIT:
So I think I have to install jedi within my anaconda environment so I did a pip uninstall jedi and installed it in my anaconda environment via conda install jedi but the problem remains.

[davidhalter]

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!

[shsymoen]

I'm having the same issue. All python plugins that I was previously using aren't working anymore; YouCompleteMe, python-mode. Therefore I tried jedi-vim as a replacement but I'm having the same problems as @mattrbrousseau. I am suspecting it got something to do with a system update I performed. I'm on Manjaro Linux and I saw that @mattrbrousseau is also using Arch.

[blueyed]

JFI: Arch upgraded to Python 3.7 recently, but only a few days ago.

[lkhphuc]

I just updated my Arch system and thing is OK now.

[shsymoen]

So what exactly should I do to get it working again?

[blueyed]

@shsymoen
Fix your Python setup.

If you get something like "undefined symbol: _Py_write_noraise" it indicates that it is broken.

Take a look at :checkhealth with Neovim, and :verbose JediDebugInfo with Vim.

[davidhalter]

Well and just BTW this might as well be an issue with how VIM compiles with Python so you might need to fix upgrade/downgrade your VIM as well as your Python version. It's just that there's really nothing we can do here. Something else was broken.

[GuiMarthe]

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.

[devlwkyan]

I'm currently having this issue, no problem with default OS' python (I'm using Arch), however the issue happens with anaconda env. Is there already a solution for this?

[blueyed]

@devlwkyan
Try :JediDebugInfo.
Also search existing ones in case it is due to a seemingly broken Python setup, e.g. when importing "subprocess" fails.
