reactjs - 找不到模块 : Error: Can't resolve '@emotion/styled/base' when running story book

Question

我构建了一个使用 @emotion/styled 的简单按钮组件用于造型。但是，在运行 npm run storybook 时，我想为这个按钮添加一个故事。我收到以下错误

Module not found: Error: Can't resolve '@emotion/styled/base' in '/directory/to/Button'

这是我在按钮组件中导入的内容:

import styled from '@emotion/styled';
import { useTheme } from '@emotion/react';

const StyledButton = styled.button`
  cursor: pointer;
  font-size: ${({ fontSize }) => fontSize};
`;

这发生在使用 @emotion/styled 的其他组件上。也是。我是否缺少额外的依赖项，还是需要向 .babelrc 文件添加任何预设？
.babelrc:

{
  "presets": [
    "@babel/preset-env",
    "@babel/preset-react",
    "@emotion/babel-preset-css-prop"
  ],
  "env": {
    "test": {
      "plugins": ["require-context-hook"]
    }
  },
  "plugins": ["react-hot-loader/babel", "@emotion"]
}

这是情感11的Break名称更改引起的问题。到目前为止，故事书内部仍在寻找v10名称以集成情感包。因此，在故事书修复它之前，您将有 2 个选项:
A. 降级为情绪 10.
B. 解决方法:

// .storybook/main.js
const path = require("path");
const fs = require("fs");
const { merge } = require("webpack-merge");

function getPackageDir(filepath) {
  let currDir = path.dirname(require.resolve(filepath));
  while (true) {
    if (fs.existsSync(path.join(currDir, "package.json"))) {
      return currDir;
    }
    const { dir, root } = path.parse(currDir);
    if (dir === root) {
      throw new Error(
        `Could not find package.json in the parent directories starting from ${filepath}.`
      );
    }
    currDir = dir;
  }
}

module.exports = {
  stories: [
    "../stories/**/*.stories.mdx",
    "../components/**/*.stories.@(ts|tsx|mdx)",
  ],
  addons: ["@storybook/addon-links", "@storybook/addon-essentials"],
  webpackFinal: async (config) => {
    return merge(config, {
      resolve: {
        alias: {
          "@emotion/core": getPackageDir("@emotion/react"),
          "@emotion/styled": getPackageDir("@emotion/styled"),
          "emotion-theming": getPackageDir("@emotion/react"),
        },
      },
    });
  },
};
