title: Unmet peer dependency installing react
body: <p>I have two related questions. I'm installing react into a new empty project. I only have a basic <code>package.json</code> file in the folder, nothing else.</p>
  
  <p>The message I get is</p>
  
  <blockquote>
    <p>+-- UNMET PEER DEPENDENCY react-addons-css-transition-group@0.14.x || 15.x.x</p>
  </blockquote>
  
  <p>First, question: Am I interpreting this correctly? Message is saying, either install the <code>react-addons-css-transition-group@0.14.x</code> package or install react version 15.x.x?</p>
  
  <p>Second, by running <code>npm install react --save</code>, I installed react version 15.5.4. If my interpretation of the message is correct, why am I getting the message? I already have react 15.5.4 installed.</p>
