如何根据环境更改 scss 样式？

Question

我正在尝试根据环境更改 style.scss。我尝试将这两个属性添加到 angular.json 但它们都没有解决我的问题：

   "styles": [
                {
                   "input": "generic/src/styles.scss"
                }
             ],
   "stylePreprocessorOptions": {
                       "includePaths": [
                                         "generic/src"
                                       ]
                               },

这是我当前的目录：

angular.json
来源
- style.scss
通用
- 来源
  - style.scss

我的也是 angular.json:

            ]
          }
        }
      }
    },

我读了一些书，但没有找到任何关于为什么它不采用这些样式的信息，但是，图标和网站图标的更改正确地做到了。我用来运行解决方案的命令如下：

ng serve generic-payment-portal-fe --configuration=test 希望你能帮帮我！

您应该能够像 environment/favicon

那样更新 fileReplacements

"fileReplacements": [
  {
    "replace": "src/environments/environment.ts",
    "with": "generic/src/environments/environment.test.ts"
  },
  {
    "replace": "src/favicon.ico",
    "with": "generic/src/favicon.ico"
  },
  {
    "replace": "src/style.scss",
    "with": "generic/src/style.scss"
  }
]
