installation

Plug Install

:PlugInstall

python3 support

go to conda env and install neovim

conda activate <env_name>
pip install neovim
pip install --upgrade pynvim

coc.nvim

prerequisites

Requirements neovim >= 0.4.0 or vim >= 8.0.1453 (run :version or vim --version to checkout your vim version) node >= 12.12

curl -sL install-node.now.sh | bash

Note: coc.nvim finds node by calling executable('node') from within vim. Check out :h g:coc_node_path to customize node path.

Install Yarn — required when building from source.

curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

Git checkout

cd ~/.config/.nvim/plugged/coc.nvim/.
git checkout release

Using vim-plug

Use release branch (recommended):

Plug 'neoclide/coc.nvim', {'branch': 'release'}

Build from source:

Plug 'neoclide/coc.nvim', { 'branch': 'master', 'do': 'yarn install --frozen-lockfile' }

Run command :PlugInstall in your (neo)vim.
