导入 scss 文件在故事书文件中不起作用

Question

我目前面临使用scss进行 Storybook React 的问题。我正在使用sb init创建故事书文件。一切正常，所有插件均已加载，但只有样式不起作用。如果我使用css文件，该样式将起作用。

@storybook/preset-scss我已经按照有关使用和配置的文档中的说明进行操作webpackFinal，但它仍然无法正常工作

这是故事书文件的示例

导入'./button.scss'; 无法正常工作

import React from 'react';
import PropTypes from 'prop-types';

import './button.scss'; -> this one not working

export const Button = ({ primary, backgroundColor, size, label, ...props }) => {
  const mode = primary ? 'storybook-button--primary' : 'storybook-button--secondary';
  return (
    <button
      type="button"
      className={['storybook-button', `storybook-button--${size}`, mode].join(' ')}
      style={backgroundColor && { backgroundColor }}
      {...props}
    >
      {label}
    </button>
  );
};

Button.propTypes = {
  primary: PropTypes.bool,
  backgroundColor: PropTypes.string,
  size: PropTypes.oneOf(['small', 'medium', 'large']),
  label: PropTypes.string.isRequired,
  onClick: PropTypes.func,
};

Button.defaultProps = {
  backgroundColor: null,
  primary: false,
  size: 'medium',
  onClick: undefined,
};

这是我的/storybook/main.js文件

const path = require('path')

module.exports = {
  "stories": [
    "../src/**/*.stories.mdx",

    "@storybook/addon-essentials",
    "@storybook/preset-scss"

  webpackFinal: async (config, { configType }) => {
    // `configType` has a value of 'DEVELOPMENT' or 'PRODUCTION'
    // You can change the configuration based on that.
    // 'PRODUCTION' is used when building the static version of storybook.

    // Make whatever fine-grained changes you need
    config.module.rules.push({
      test: /\.scss$/,
      use: ['style-loader', 'css-loader', 'sass-loader'],

我遇到了类似的问题，以下 Github 线程为我修复了：

故事书Issue-12464

以下是摘要（确保您已安装 scss）：

1. 就我而言，我没有安装preset-scss 插件。我是通过使用以下方法做到的：

   npm install @storybook/preset-scss --save

在你的情况下，预设 scss 插件似乎已经存在。

2. 注释掉main.js文件中的配置规则：

   config.module.rules.push({

   test: /\.scss$/,

   use: ["style-loader", "css-loader", "sass-loader"],

   include: path.resolve(__dirname, "../"), });

3. 如果这不起作用，请尝试将您的 scss 文件导入到preview.jsStorybook config 文件夹中。

   .storybook > preview.js > import your CSS file;
