Healthcheck fails RPC test

See original GitHub issue

nvim --version: NVIM v0.4.4 (+acl +iconv +tui)
Operating system/version: NixOS (relevant parts of configuration.nix shown below)

environment.systemPackages = with pkgs; [
  neovim
  (python3.withPackages(ps: with ps; [ pynvim ueberzug])
  ...
]

nvim +'checkhealth rnvimr':

health#rnvimr#check
========================================================================
## OS
  - OK: Name: Linux

## Ranger
  - OK: Version: ranger 1.9.3

## Python
  - OK: Version: 3.8.5 (default, Jul 20 2020, 13:26:22) [GCC 9.3.0]

## Pynvim
  - OK: Version: 0.4.1

## Ueberzug (optional)
  - OK: Ueberzug is ready

## RPC
  - ERROR: RPC: timeout 3s

Describe the bug

I am told by the healthcheck that RPC is timing out.

Otherwise, I seem to be able to use the plugin just fine (even when I didn’t have pynvim or ueberzug installed…).

Am I missing any additional dependencies?

Expected behavior

Unclear what the implications of this error message are, but it shouldn’t be appearing.

@j-hui I’ve reproduced this issue: it was because of using separate Python for NVIM:

" init.vim
let g:python3_host_prog=~/.venvs/vim3/bin/python

So pynvim package isn’t installed in system Python3 and in this case NVIM starts, it’s health-check is ok but ranger can’t load rnvimr plugins (although succsesfully starts) so RPC doesn’t work.

Looks like in this case ranger uses Python without pynvim package.
