body: <p>I have Cloud functions project and i moved the project from my old laptop to my new laptop.</p>
  
  <p>I have installed everything that necessary. My problem is when i try "firebase deply" it gives me that error: </p>
  
  <p><code>!  functions: package.json indicates an outdated version of firebase-functions.
   Please upgrade using npm install --save firebase-functions@latest in your functions directory.</code></p>
