Reactjs React故事书postss配置

我正在为我的React应用程序设置一本故事书。我面临一个关于PostCs的问题，显然我的故事书配置没有处理PostCs，我的风格被完全忽略

这是my package.json：

{

  ...

  "devDependencies": {

    "@storybook/addon-actions": "^6.2.8",

    "@storybook/addon-essentials": "^6.2.8",

    "@storybook/addon-links": "^6.2.8",

    "@storybook/addon-postcss": "^2.0.0",

    "@storybook/react": "^6.2.8",

    "css-loader": "2.1.1",

    "extract-css-chunks-webpack-plugin": "4.3.2",

    "postcss-cssnext": "^3.1.0",

    "postcss-csso": "^3.0.0",

    "postcss-loader": "^3.0.0",

    "style-loader": "^2.0.0"

  }

}

这是我的main.js：

module.exports = {

  "stories": [

    "../src/**/*.stories.@(js|jsx|ts|tsx)",
  ],

  "addons": [

    "@storybook/addon-links",

    "@storybook/addon-essentials",

    "@storybook/addon-postcss"
  ]
}

欢迎任何帮助
