title: I upgraded node but it still uses the wrong version?
body: <p>I just ran <code>brew upgrade node</code> and it successfully upgraded Node to version >=4, however <code>node --version</code> returns the old version:</p>
  
  <pre><code>My-MacBook-Pro:~ me$ node --version
  v2.3.0
  My-MacBook-Pro:~ me$ brew upgrade node
  Error: node 4.1.1 already installed
  </code></pre>
  
  <p>How can I have node use the newest version instead of 2.3.0?</p>
