body: <p>I am trying to use <a href="https://github.com/TheSeamau5/elm-storage/" rel="nofollow noreferrer">https://github.com/TheSeamau5/elm-storage/</a> with elm 0.18</p>
  
  <p>when trying to run elm-reactor, I get this error:</p>
  
  <ul>
  <li>Uncaught TypeError: runElmProgram is not a function</li>
  </ul>
  
  <p>but when I try to run: elm make src/Exercises.elm --warn --output elm.js</p>
  
  <p>then I get no warnings but this errors:</p>
  
  <ul>
  <li>Uncaught ReferenceError: Elm is not defined</li>
  <li>Uncaught TypeError: Cannot read property 'Native' of undefined</li>
  </ul>
