title: Vim Prettier with vim Plug
body: <p>I tried installing Prettier with vim plug but doesn't work.
  PlugInstall installs successfully without any errors.
  but :prettier command says it's not a command</p>
  <p>vimrc:</p>
  <pre><code>Plug 'prettier/vim-prettier', { 'do': 'yarn install' }
  </code></pre>
