title: I can't open Cypress on Mac: Cypress not found
body: <p>I've checked through the answers on S.O and so far none have worked for me.</p>
  
  <p>I put my question in a video.  <a href="https://www.dropbox.com/s/dt5eg86wjlww7u4/can%27t%20open%20cypress.mp4?dl=0" rel="nofollow noreferrer">Watch it here</a> </p>
  
  <p>What went wrong?  It was working fine yesterday?</p>
  
  <p>What I've done so far: </p>
  
  <p>Re installed cypress</p>
  
  <p>tried to open with : <code>.node_modules\.bin\cypress open</code></p>
  
  <p>then tried:  <code>npx cypress open</code></p>
  
  <p>Got the following message</p>
  
  <pre><code>No version of Cypress is installed in: /Users/jacquelinegeorge/Library/Caches/Cypress/3.4.0/Cypress.app
