title: React Moment problem on DatePicker when using moment (Maybe dependencies)
body: <p>I'm using DatePicker and I can't set the default Values, I tried this:</p>
  
  <p>I import the moment like this:</p>
  
  <pre><code>import moment from 'moment';
  
  //And then: 
  
  &lt;DatePicker 
     defaultValue={moment('2015/01/01', 'YYYY/MM/DD')}
  /&gt;
  
  //Also tried this
  
  &lt;DatePicker 
     defaultValue={moment('2015/01/01')}
  /&gt;
  </code></pre>
  
  <p>But I got this error:
  "Type 'import("C:/git/my_project/node_modules/moment/moment").Moment' is not assignable to type 'moment.Moment'.
   Types of property 'add' are incompatible."</p>
  
  <p>I can't find where is my error</p>
  
  <p>When I type npm ls moment and npm ls @types/moment. This is the result:</p>
