【问题描述】：
我使用 angular 4 以及 Webpack 和 Yarn 作为包管理器。使用 JIT 开始我的项目并尝试使用 ngtools/webpack 迁移到 AOT。 尝试使用以下方法构建我的项目时：
yarn build
我得到错误：
ERROR in window is not defined
我已从我的项目中删除所有窗口引用，以确保我的项目中不会发生错误。 我的结论是它发生在我正在加载的外部模块中。不知道是哪个，因为错误消息似乎被破坏了。 尝试以各种不同的方式包括它，主要是这些问题： Expose jQuery to real Window object with Webpack , https://stackoverflow.com/a/28989476/2823310 但目前对我没有任何帮助。
我认为这段代码：
var globalWindow = {};
globalWindow.$ = globalWindow.jQuery = require("jquery");
new webpack.DefinePlugin({
window: globalWindow
})
是解决问题的方法，但会产生更多相同的问题：
ERROR in document is not defined
如何在窗口对象实际存在之前对窗口对象进行全局引用（AOT - 提前不应该真正知道真正的窗口对象）。 Angular 4 和 webpack 的 AOT 是否还不够成熟？因为网络上没有太多关于它的信息。
似乎真的与这个话题有关： window is not defined using Angular4 + AoT + Webpack2 但没有人回答。
