After typing :MarkdownPreview nothing happens

Hi, I have installed this plugin using vim plug however when I type the command i.e MarkdownPreview nothing happens. I am fairly new to nvim but not sure why this is happening don’t have a lot of plugins or anything, running Arch linux. Here is a snippet of my plugins.vim file

  1 if empty(glob('~/.config/nvim/autoload/plug.vim'))
  2   silent !curl -fLo ~/.config/nvim/autoload/plug.vim --create-dirs
  3     \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
  4   "autocmd VimEnter * PlugInstall
  5   "autocmd VimEnter * PlugInstall | source $MYVIMRC
  6 endif
  7 
  8 call plug#begin('~/.config/nvim/autoload/plugged')
  9 
 10     " Better Syntax Support
 11     Plug 'sheerun/vim-polyglot'
 12     " File Explorer
 13     Plug 'scrooloose/NERDTree'
 14     " Auto pairs for '(' '[' '{'
 15     Plug 'jiangmiao/auto-pairs'
 16     " MARKDOWN PLUGINS
 17     Plug 'plasticboy/vim-markdown'
 18     Plug 'iamcco/markdown-preview.nvim', { 'do': { -> mkdp#util#install() }, 'for': ['markdown', 'vim    -plug']}
 19 call plug#end()

As for init.vim I just pasted the default settings and added the firefox as the browser.

I think the npm installs work differently in arch than in other distros.

I use packer for my nvim plugins, and: The config use {'iamcco/markdown-preview.nvim', run = 'cd app && npm install'} doesn’t work for me, even if I have npm installed.

But this one use {'iamcco/markdown-preview.nvim', config = "vim.call('mkdp#util#install')"} works well.

The install proposed in #329 should be the prebuild I think, this would cause less bugs.

@ikey4u should be fixed now.

@Abdulee your plugin install is not complete. do call mkdp#util#install() again or go to plugin’s app directory run yarn install or npm install
