Neovim: "vim-llp: python required" although working flawlessly in VIM

[bjce]

Expected behavior

Being able to see a compiled .tex file after entering :LLPStartPreview + should not give the message vim-llp: python required as both bash aliases python and python3 redirect to python 3.7.3

Actual behavior

afert typing $ neovim, I get the message

vim-llp: python required
Press ENTER or type command to continue

Opening a .tex file with neovim, I cannot make the command ':LLPStartPreview' (although it works fine with vim

Steps to reproduce

Tell us how it occurs

1. Opening a tex file with command nvim example.tex
2. The following message appears:

   vim-llp: python required
   Press ENTER or type command to continue

3. Inside the .tex file, when entering the command :LLPStartPreview, I get E492: Not an editor command: LLPStartPreview

I had the same problem, just make sure you have installed python-pip and then sudo pip install neovim. It should solve the problem.

Well, here's my output of this command, yet I still can't start LLPStartPreview in neovim

sudo pip3 install neovim
Requirement already satisfied: neovim in /usr/lib/python3/dist-packages (0.3.0)

And I use the coc and vim-plug plugins which both rely on python to work. Any other suggestions?

Thanks for replying. I solved by installing textlive on macOS.
