When opening a tex file I get, for vimPlugins.coc-texlab, the following popup:
TexLab Server is not found, download from GitHub?
1. Yes
2. Cancel
I get a similar error when trying with vimPlugins.coc-vimtex.
Any advice on how to solve above problem?
I think the following are the relevant parts of my Home Manager configuration:
programs.neovim.enable = true;
programs.neovim.coc.enable = true;
programs.neovim.plugins = [
# …
pkgs.vimPlugins.coc-texlab
# …
];

### Description
Hello, it's my first time posting an issue I have.
I install… ed vimtex, coc.nvim alongside other plugins through Vim_Plug and each time I open a `.tex` file i get an error saying `[coc.nvim] vimtex not loaded, please check your runtimepath`. I searched if this issue was already treated and I found these two posts [#18](https://github.com/neoclide/coc-vimtex/issues/18) and [#6](https://github.com/neoclide/coc-vimtex/issues/6) but it didn't help me. My vimtex installation works well (`:VimtexInfo` works and I added `let g:tex_flavor = 'latex'` to my `.vimrc`) so it isn't like the above posts' issue.
Here is the output of `:CocInfo`:
```

```
So apparently there is a problem with `vimtex#re#deoplete` but I don't even have it installed, I don't quite understand where the problem is, if it's on vimtex side or coc.nvim side.
Here is the main part of my `.vimrc`:
```vim
" vim_plug plugin
let data_dir = has('nvim') ? stdpath('data') . '/site' : '~/.vim'
if empty(glob(data_dir . '/autoload/plug.vim'))
silent execute '!curl -fLo '.data_dir.'/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim'
autocmd VimEnter * PlugInstall --sync | source $MYVIMRC
endif
" beginning of plugin list
call plug#begin()
Plug 'lervag/vimtex' " latex
let g:tex_flavor = 'latex'
Plug 'neoclide/coc.nvim', {'branch': 'release'}
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }
Plug 'junegunn/fzf.vim' " fuzzy search tool
Plug 'godlygeek/tabular' " markdown plugins
Plug 'plasticboy/vim-markdown'
Plug 'iamcco/markdown-preview.nvim', {'do': { -> mkdp#util#install() }, 'for': ['markdown', 'vim-plug']}
Plug 'morhetz/gruvbox' " color theme
Plug 'tmhedberg/SimpylFold' " fix intensive folding when indent
Plug 'vim-scripts/indentpython.vim'

" Plug 'vim-syntastic/syntastic' " check syntax for python etc
Plug 'preservim/nerdtree' " tree to navigate in project's files
" Plug 'kien/ctrlp.vim' " <C-p> enable fuzzy file search
call plug#end()
" overall config

" vimtex config
let g:vimtex_enabled = 1
let g:vimtex_view_general_viewer = 'mupdf'
let g:vimtex_compiler_method = 'latexmk'
let g:vimtex_compiler_latexmk_engines = {
\ '_' : '-xelatex'
\}
let g:vimtex_complete_enabled = 1
let g:vimtex_fold_enabled = 1 " folding tex sections
let g:vimtex_complete_enabled = 0
" coc config
set hidden cmdheight=2 updatetime=300 shortmess+=c
" trigger completion
inoremap <silent>expr> <c-m> coc'refresh()
let g:coc_global_extensions = [
" \ 'coc-vimtex',
" \ 'coc-pairs'
" \]
```
While submitting this issue I noticed that in the `minima.vim`, vimtex is called in `~/vim/bundle/vimtex` but mine is installed in `~/vim/plugged/vimtex`, maybe this can be the problem(?)
I read the documentation about `vimtex-complete-coc.nvim` but it didn't help me further so I am now trying to submit an issue.
As I said I am new in this issue submitting so please ask me if I forgot to add something.
Thank you in advance for your help!

you are missing the actual program texlab as the message mentions. you didn’t say what happened after answering “yes” but chances are it will fail as the download texlab executable wont work.
add pkgs.texlab to your environment.collect and add to PATH runtimeinputs of neovim plugin dependencies · Issue #352738 · NixOS/nixpkgs · GitHub

Thanks, adding pkgs.texlab to home.packages solved it!
@anders , I changed the post to help category and you can now mark teto’s answer as solution.
