Unable to Run YouCompleteMe in neovim

Question

I use Manjaro (5.6.7 Kernel), I am trying to install YCM on neovim. I did it before, but it was vim, and I used vundle, this time I am using vim-plug. I get this message when I launch newvim.

YouCompleteMe unavailable: requires Vim compiled with Python (3.5.1+) support.

Thanks!

Do you have the [python-pynvim](https://www.archlinux.org/packages/community/any/python-pynvim/) package installed? Can you run `:py3 print('hello')` from inside NeoVim? — filbranden, May 02 '20 at 19:33

YouCompleteMe breaks so often, that I wrote down the steps to resurrect it:

1. Attempt reinstalling YCM:

$ python <DOTFILE_PATH>/vim/plugged/youcompleteme/install.py --clang-completer

2. Received the following error?

ERROR: found static Python library (/Users/USER/.pyenv/versions/3.7.2/lib/python3.7/config-3.7m-darwin/libpython3.7m.a) but a dynamic one is required.

Then:

$ export PYTHON_CONFIGURE_OPTS="--enable-framework"
$ pyenv install 3.7.2

3. If neovim throws error "[...] requires Vim compiled with Python (2.7.1+ or 3.4+) support" on start, then:

$ python3 -m pip install --user --upgrade pynvim

Replace 3.7.2 with your actual python3 version. No need to stick to an old version, just because I wrote this note a while back.

Thanks, this helped. In my case I was missing the `pynvim` package in my virtualenv. — Pierre, Nov 19 '20 at 07:40
