body: <p>How I can find out package installed globally with Yarn or npm?
  (I can't remember package installed with which one!)</p>
  
  <p><em>let me describe more</em>:</p>
  
  <p>I had install Vuejs with help its installation document; On that described I can use tow way to install it:</p>
  
  <pre><code>npm install -g @vue/cli
  # OR
  yarn global add @vue/cli
  </code></pre>
  
  <p>and now I can remember how I instaled VueJS, with npm or yarn?! I have this problem with <strong>JHipster</strong> and <strong>Quasar Framework</strong> and <strong>Vuetify</strong>, after a while I forget how they had installed on my system! :-/</p>
