title: How to update pre-existing dependency when using create-react-app?
body: <p>I am using <code>create-react-app</code> for a project. I installed various eslint plugins etc, however, we all know that create-react-app already comes with certain dependencies that are not shown in <code>package.json</code>. </p>
  
  <p>I want the newest <code>eslint</code> version which is currently 5.3.0. Create-react-app comes with 5.16.0. WITHOUT EJECTING, how do I bring this dependency to the newest version without breaking everything?</p>
  
  <p>I get the following error:</p>
  
  <pre><code>The react-scripts package provided by Create React App requires a dependency:
  
    "eslint": "^5.16.0"
  
  Don't try to install it manually: your package manager does it automatically.
  However, a different version of eslint was detected higher up in the tree:
  
  :\node_modules\eslint (version: 5.3.0)
  </code></pre>
