升级项目时，数据路径“”在 Angular 13 中不能有其他属性（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 文件中将 styleext 重命名为 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属性？

谁能帮我解决这个问题？

提前致谢！

只需从您的生产环境中删除 "extractCss": true，即可解决问题。

原因是 extractCss 已被弃用，默认情况下它的值为 true。在此处查看更多信息：Extracting CSS into JS with Angular 11 (deprecated extractCss)
