title: Brew install chromedriver not working?
body: <p>I am using MacOS, when I tried to install chromedriver using homebrew</p>
  
  <pre><code>brew install chromedriver
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>Error: No available formula with the name "chromedriver" 
  It was migrated from homebrew/core to caskroom/cask.
  You can access it again by running:
  brew tap caskroom/cask
  </code></pre>
  
  <p>I typed <code>brew tap caskroom/cask</code> but chromedriver is still not installed.
  Can someone please help me on this? Thanks!</p>
