[vim-hug-neovim-rpc] requires one of `:pythonx import [pynvim|neovim]`

Hi! Is this happening with vim or neovim? Are you on the latest version of the config? Any modifications made to the config?
And are the virtualenvs python2 or python3?

[ajinzrathod]

Yes, I am using the latest version.

I have 3 python versions in my PC

1. python2.7
2. python3.6
3. python3.7

I have installed Virtual Envs in 3.7
Yes, I have made certain changes.
See here

But I have only added Syntastic Check and NERDTree

Its working totally fine WITHOUT virtualenv
It causes error only in virtualenv

And I am using vim

Please solve my issue, without this, autocomplete is not working, and I do not want to shift to emacs or sublime.
Please help me

The most probable cause is that you installed all the dependencies outside the virtualenv, but you are now using the editor from inside the virtualenv.
You have two options: you can launch the editor from outside the virtualenv, or you can install the config dependencies inside the virtualenv too.

DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.
greenlet (0.4.16)
msgpack (1.0.0)
neovim (0.3.1)
numpy (1.19.0)
opencv-python (4.2.0.34)

pkg-resources (0.0.0)
pynvim (0.4.1)
scikit-video (1.1.11)
scipy (1.5.0)
setuptools (39.0.1)

I do not want to launch outside venv.

You can see I have already installed pynvim and neovim. Correct me if I m wrong?

Ok, I'm able to reproduce the issue here, it seems like a bug/problem in Deoplete while in Vim. I'll try to see if I can find a fix, but I can't promise anything. In the meantime, an option is to switch to NeoVim, which doesn't have this problem.

[ajinzrathod]

Ok. Thanks

@pilot513
you should try
pip install neovim inside Virtual Environment

[pilot513]

I install neovim. Now probles solved in vim/nvim.
Thanks.

[fisadev]

ok, that's super weird. In theory that package was deprecated and replaced with pynvim, and installing pynvim in the venv the editor should be able to do "import neovim", because pynvim keeps that for compatibility.

[ajinzrathod]

I created another virtual environment and tried:

pip install neovim
pip install pynvim
pip install vim
pip install jedi

And its working fine in my new virtual environment.

I think there is some issue with virtual environment.
Thank you 👍
