title: Vue-socket.io install failing, cannot find 'package.tgz'
body: <p>I'm trying to install the dependencies for a project that uses <code>vue</code> and <code>vue-socket.io</code> using a standard <code>npm install</code> command, but the installation keeps failing because <code>vue-socket.io</code> is looking for a <code>package.tgz</code> file that I apparently don't have. I keep getting this error message:</p>
  
  <pre><code>       Error extracting /Users/macpro/.npm/vue-socket.io/2.1.0/package.tgz 
  archive: ENOENT: no such file or directory, open '/Users/macpro/.npm/vue-
  socket.io/2.1.0/package.tgz'
  </code></pre>
  
  <p>I've tried to install the package by itself and I keep getting the same error. I've double-checked that I have the right dependencies and that I'm installing the correct versions. </p>
  
  <p>Does anyone know why it keeps looking for this file? Or what it is I'm missing in my install? It seems from the documentation that I should be able to just use <code>npm i vue-socket.io</code>.</p>
  
  <p>Thanks in advance!</p>
