I'm trying to install neovim on Windows and import my previous init.vim file. I've previously defined my snippets in ultisnips. I'm using windows and ahve tested this in another version of windows and it works, however, at the moment when I run

:checkhealth

I get the following error:

## Python 3 provider (optional)

But I do have python 3.7 installed. I can run python in cmd / powershell, and I can import neovim python module without any issues. Does someone know how to get neovim to pick up python?

Make sure you have Python3 installed, the following answer also works with Python2.

Check for help:

:help provider-python

Go to the PYTHON QUICKSTART and you will see one of this two options:

  • For Python 2 plugins:
  • For Python 3 plugins:

Because you're problem is with python 3 follow this steps that are mentioned in For Python 3 plugins:

1. Make sure Python 3.4+ is available in your $PATH.
2. Install the module (try "python" if "python3" is missing): >
   python3 -m pip install --user --upgrade pynvim

This should fix the problem, if it persist then make sure the right path is being used, go to ~/.vimrc and add the following:

For python3:

let g:python3_host_prog = '/path/to/python3'

For Python2:

let g:python_host_prog  = '/path/to/python'

Note: I found this in PYTHON QUICKSTART if you continue reading you will find it.

To know the location of python use:

  • For Linux and Mac
which python3

Use :checkhealth again and it should output the following:

## Python 3 provider (optional)
  - INFO: Using: g:python3_host_prog = "/usr/local/bin/python3"
  - INFO: Executable: /usr/local/bin/python3
  - INFO: Python version: 3.9.1
  - INFO: pynvim version: 0.4.2
  - OK: Latest pynvim is installed.

    For windows you should be able to use `where` instead of which, worked for me personally. But I've seen some other posts which state where isn't the best – karizma Jul 02 '21 at 18:20
  • @karizma That's why I put a link instead of the actual command. – Classy-Bear Sep 22 '21 at 18:38
  • For anyone struggling whit it, you actually need to point to the actual executable, not only the path, e.g.: let g:python3_host_prog = 'C:\Users\YOURUSERNAME\AppData\Local\Programs\Python\Python310\python.exe' – Balu Dec 06 '21 at 09:06
  • This solution DOES NOT work for me, even after the edit in the last comment of @Balu – Antonio Sesto Feb 04 '23 at 10:45

It seems, that neovim is confusing python 2 and python 3 somehow. For me it worked just to have renamed python executable in PATH of python 2, that is python.exe -> python2.exe, and now it seems to work fine. However it is maybe not the perfect solution.

I just solved this problem. So let me say what I did.

In the beginning, I used the python3.8.8, which will create the same issues. I tried to pip install neovim and failed.

Then I replace the python3.8.8 with python3.8.1. Everything is OK~

So change the version of Python?

  1. Locate the path to the python3 executable using one of these methods. Copy the path. For me, it was C:\Users\money\AppData\Local\Programs\Python\Python310.

  2. Then, add this directory to your PATH variable. Search for "View advanced system settings" > "Environment Variables" > "System Variables" > "Path" > "Edit" > "New" and paste the directory there , save and exit.

  3. You should be able run python commands from the terminal now.

  4. Install the neovim python module by doing pip3 install pynvim in the terminal.

Try :checkhealth provider again. It should work.
