How to enable python provider for Neovim installed via flatpak?

  • 772

I'm new to flatpak so I don't really know how exactly it works.

I tried to install python3 on my native system using apt and install pynvim with pip3 install --user --upgrade pynvim. (I did this when I was using snap and it's perfectly fine)

But still, my neovim cannot seem to have the provider working. This following is my health check result.

## Python 3 provider (optional)
  - INFO: Disabled (g:loaded_python3_provider=1).  This might be due to some previous error.
  - WARNING: No Python executable found that can `import neovim`. Using the first available executable for diagnostics.
  - ERROR: Python provider error:
    - ADVICE:
      - provider/pythonx: Could not load Python 3:
          /usr/bin/python3 does not have the "neovim" module. :help |provider-python|
          /usr/bin/python3.7 does not have the "neovim" module. :help |provider-python|
          python3.6 not found in search path or not executable.
          python3.5 not found in search path or not executable.
          python3.4 not found in search path or not executable.
          python3.3 not found in search path or not executable.
          /usr/bin/python is Python 2.7 and cannot provide Python 3.
  - INFO: Executable: Not found

EDIT1:

I made some progress on this. I found that the neovim flatpak app has host enabled so that I can access my native python3 executable through /var/run/host/usr/bin/python3. However, the path to everything that python3 depends on will need to be prepended with /var/run/host/, which is still not happening. Here is the new health check message.

Thank you!
