ReactJS findDOMNode 和 getDOMNode 不是函数

我正在用ReactJS和Flux构建一个web应用程序，我试图使用方法findDOMNode获取当前div的 node ，我得到了下一个错误:

Uncaught TypeError: React.findDOMNode is not a function

所以，我试着用getDOMNode，我得到了同样的错误:

Uncaught TypeError: React.getDOMNode is not a function

我正在使用npm构建JS，我在其中使用以下方法的代码:

var React = require('react');
var stores = require('../stores');
var MessagesUserContainer = require('./messageusercontainer');
var ChatStore = stores.ChatStore;
var owner = stores.getOwner();

var MessagesList = React.createClass({

    getInitialState: function(){
        return {'muc': []};
    },
    componentDidUpdate: function(){
        var node = React.findDOMNode(this); //Error here
        node.scrollTop = node.scrollHeight;
    },
    render: function(){
        return (
                <div className="chatScroll">
                    {this.state.muc}
                </div>
            )
    }
});

module.exports = MessagesList;

ReactJS verion: 0.14.0

EDIT

正如答案中指出的，DOM库从v0开始.14.0超出了React核心，所以我对代码做了一些更改:

var React = require('react');
var ReactDOM = require('react-dom');
var stores = require('../stores');
var MessagesUserContainer = require('./messageusercontainer');
var ChatStore = stores.ChatStore;
var owner = stores.getOwner();

var MessagesList = React.createClass({

    getInitialState: function(){
        return {'muc': []};
    },
    componentDidUpdate: function(){
        var node = ReactDOM.findDOMNode(this);
        node.scrollTop = node.scrollHeight;
    },
    render: function(){
        return (
                <div className="chatScroll">
                    {this.state.muc}
                </div>
            )
    }
});

module.exports = MessagesList;

但我还有一个问题:

Uncaught Error: Invariant Violation: findDOMNode was called on an unmounted component.
