Angular 4通用Node.js server.js错误

我正在构build一个Angular 4 CLI应用程序，并尝试使用新内置的Universal进行SSR。 所有似乎工作正常，直到我尝试运行节点server.js

下面的错误被返回：

var crypto = require('crypto'); ^ TypeError: require is not a function at Object.webpackEmptyContext.keys (/dist-server/server.js:156480:14) at __webpack_require__ (/dist-server/server.js:20:30) at Object.<anonymous> (/dist-server/server.js:156469:20) at __webpack_require__ (/dist-server/server.js:20:30) at Object.module.exports.raw (/dist-server/server.js:42461:18) at __webpack_require__ (/dist-server/server.js:20:30) at Object.<anonymous> (/dist-server/server.js:42340:15) at __webpack_require__ (/dist-server/server.js:20:30) at Object.<anonymous> (/dist-server/server.js:77201:22) at __webpack_require__ (/dist-server/server.js:20:30) 

任何angular4普遍专家在那里？
