react material-ui cdn 引入的問題

我在引入material-ui 的CDN版本時會出現(xiàn)react-transition-group/TransitionGroup未定義的問題。

material-ui 的UMD代碼如下


(function webpackUniversalModuleDefinition(root, factory) {

if(typeof exports === 'object' && typeof module === 'object')
    module.exports = factory(require("./react"), require("./react-dom"), require("react-transition-group/TransitionGroup"));
else if(typeof define === 'function' && define.amd)
    define("material-ui", ["react", "react-dom", "react-transition-group/TransitionGroup"], factory);
else if(typeof exports === 'object')
    exports["material-ui"] = factory(require("./react"), require("./react-dom"), require("react-transition-group/TransitionGroup"));
else
    root["material-ui"] = factory(root["React"], root["ReactDOM"], root["react-transition-group/TransitionGroup"]);

})(typeof self !== 'undefined' ? self : this

可以看到material-ui是依賴react-transition-group/TransitionGroup的，可是我不知道該怎么引入。
