title: Cannot find module 'tailwindcss'
body: <p>I am trying out tailwindcss with my Vue project and while I solved some issue I had with the routing (while trying to break down my code into smaller components), I think I broke something else.</p>
  
  <p>The code was compiling before I added my new routes. I can't seem to find what is wrong in this case.</p>
  
  <pre><code>Failed to compile.
