Question

我已经在这里搜索了答案，但还无法正常工作。

运行“ node dist / server.js”时出现以下错误消息

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)

我已经读过，在这种情况下，我应该在文档（和窗口）周围放置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，这些更改将被删除，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“节点dist / server.js”，错误仍然保持不变

未在通用角度文件上定义文档，更改将无法保存
