angular - 警告 : 1 rules skipped due to selector errors: legend + * -> Cannot read property 'type' of undefined

Question

自从我从 Angular v8 升级到 Angular v13 并从 v5.0 Bootstrap 到 v5.2 以来，我收到了这个警告，每次我按 ctrl+s 编译时 si 都很慢并且这个警告再次出现
这是我的 package.json 文件中的依赖项

我有同样的问题，但我能够通过将以下配置属性添加到“angular.json”文件的“生产”build设置中来消除此警告:

            "optimization": {
              "scripts": true,
              "styles": {
                "minify": true,
                "inlineCritical": false
                },
              "fonts": true
            },
            "outputHashing": "all",
            "sourceMap": false,
            "namedChunks": false,
            "aot": true,
            "extractLicenses": true,
            "vendorChunk": false,
            "buildOptimizer": true

(注意:您的项目中可能只需要其中的一些来解决您的问题)
