[Help] How to set up Python 3 provider
Closed this issue · 9 comments
I am trying to get set up using molten-nvim but I seem to be missing a step for configuring Python and neovim because my Python 3 provider is not set. I am using a virtual environment and this is the output from :checkhealth provider:
provider: health#provider#check
Clipboard (optional) ~
- OK Clipboard tool found: xsel
Python 3 provider (optional) ~
- Disabled (g:loaded_python3_provider=0).
Python virtualenv ~
- $VIRTUAL_ENV is set to: /home/henry/workspace/ncapi/env
- Python version: 3.10.12
- OK $VIRTUAL_ENV provides :!python.
Ruby provider (optional) ~
- Disabled (g:loaded_ruby_provider=0).
Node.js provider (optional) ~
- Disabled (g:loaded_node_provider=0).
Perl provider (optional) ~
- Disabled (g:loaded_perl_provider=0).
When I run :checkhealth molten I get this:
molten: require("molten.health").check()
molten-nvim ~
- OK NeoVim >=0.9
- ERROR molten-nvim requires a Python provider to be configured!
I must be missing something very basic! I have pynvim installed in the virtual environment, was following the getting started guide.
I would appreciate any suggestions!
should be on by default, can you link your config? You must be disabling it somewhere, we can find it.
I just added my config to a repo: https://github.com/hrodmn/nvim
init.lua sources myinit.lua which sets vim.g.python3_host_prog but that doesn't seem to be taking effect.
https://github.com/hrodmn/nvim/blob/main/lua/configs/lazy.lua#L37 1
This is the offending line
Footnotes
Unfortunately it did not fix everything - I think it helped since I can see that the molten actions are available now, but I am still not getting a Python 3 provider. Maybe one of the other disabled plugins is breaking things.
I will try commenting out the whole list of disabled plugins and try to identify the culprit(s).
Definitely share results. I might make an FAQ doc with a bunch of common setup issues. There are a few now
I have a similar issue but on Windows, I set the vim.g.python3_host_prog to a dedicated env, but the checkhealth fails, I think it will be useful to add where it found the installation that uses.
Where can I find the bin that uses?

ok seems related with pyenv-win, because if I delete C:\Users\andre\AppData\Roaming\Python\Python312 the molten's checkhealth passes.
Ok I solved. If Neovim was installed using --user it appears on C:\Users\andre\AppData\Roaming\Python\Python312 so a solution is to do pip install --force --user jupiter-client
Or to make all clearer. Delete the Pyenv-win env. Create a new one install everything and then duplicate it.
