库的StylePreprocessOptions，在angular.json中应该放在哪里？

我正在尝试使用

stylepreprocessions

为库项目包含到我的变量文件夹的路径，如下所示：

"stylePreprocessorOptions": {
  "includePaths": [
    "styles/variables"
  ]
}

然后我使用

@import'colors'。但在发球时它不起作用：

@import 'colors';
       ^
      Can't find stylesheet to import.

以下是angular.json中的完整库：

        "ui-table": {
            "root": "libs/ui/table",
            "sourceRoot": "libs/ui/table/src",
            "projectType": "library",
            "prefix": "xxx",
            "architect": {
                "build": {
                    "builder": "@angular-devkit/build-ng-packagr:build",
                    "options": {
                        "tsConfig": "libs/ui/table/tsconfig.lib.json",
                        "project": "libs/ui/table/ng-package.json",
                        "stylePreprocessorOptions": {
                            "includePaths": [
                                "styles/variables"
                            ]
                        }
                    }
                },
                "lint": {
                    "builder": "@angular-devkit/build-angular:tslint",
                    "options": {
                        "tsConfig": ["libs/ui/table/tsconfig.lib.json"],
                        "exclude": ["**/node_modules/**"]
                    }
                }
            },
            "schematics": {
                "@nrwl/schematics:component": {
                    "styleext": "scss"
                }
            }
        },


如何在Angular中的库中使用
样式预处理器

谢谢
 不在angular.json中

在libraries的ng-package.json中包含带有
styleIncludePaths
的scss文件夹路径

"lib": {
    "entryFile": "src/public-api.ts",
    ...
    "styleIncludePaths": [
        "relative/path/to/scss/folder"
    ]
    ...
}

最后从引用的scss文件夹导入文件，不带前缀路径，如下所示

@import "filename";

@GreatHawkeye请接受这一正确答案，如果它能像我一样解决你的问题。
