angular - 文档未在 Angular Universal 上定义，更改不会被保存

问题描述

我已经在这里寻找答案，但我还不能让它工作。

运行“node dist/server.js”时收到以下错误消息

ReferenceError: document is not defined
at new BrowserPlatform (C:\cmder\Project\dist\server.js:164638:25)
at Object.<anonymous> (C:\cmder\Project\dist\server.js:164682:29)
at __webpack_require__ (C:\cmder\Project\dist\server.js:20:30)
at Object.<anonymous> (C:\cmder\Project\dist\server.js:136679:77)

我读过在这种情况下我应该在文档（和窗口）周围放置一个 if 语句。我在 dist/server.js 文件中所做的：

var BrowserPlatform = /** @class */ (function () {
function BrowserPlatform() {
    this.emptyByteString = '';
    if(document) {this.document = document;}
    if(window) {this.window = window;}
    this.base64Available = typeof atob !== 'undefined';
}

现在，当我运行“npm run webpack:server”时，这些更改会被删除，所以我在这里的原始文件只有“this.document = document;” 依此类推，一旦我进入“node dist/server.js”，错误仍然存​​在
