升级项目时，数据路径“”在 Angular 13 中不得具有附加属性（extractCss）

Question

我在将项目从 Angular 8.2.1 升级到 Angular 13 版本时遇到问题。

在准备构建时成功升级后，出现以下错误。

Data path "" must NOT have additional properties(extractCss).

我已经在 angular.json 文件中重命名为styleext with style，但仍然无法找到此错误的根本原因。

angular.json 文件如下。

如何摆脱这个额外的财产？

谁能帮我这个？

只需将其"extractCss": true从生产环境中删除即可解决问题。

原因是 extractCss 已被弃用，并且它的值默认为 true。在此处查看更多内容：使用 Angular 11 将 CSS 提取到 JS（已弃用 extractCss）
