reactjs - 如何解决使用情感: 'default' is not exported by @emotion\memoize\dist\memoize. cjs.js时汇总构建错误

Question

我正在尝试为我们的企业库构建标准化的 react 按钮组件。我希望能够使用 @emotion/styled 生成样式化的 react 组件。我们使用 rollup 作为我们的包构建器，它从 typescript 转换为 esm 和 commonjs。当我运行构建时，我收到以下错误: 错误:node_modules\@emotion\memoize\dist\memoize.cjs.js 未导出“默认” node_modules\@emotion\is-prop-valid\dist\is-prop-valid.esm.js (1:7) 1:从'@emotion/memoize'导入memoize;

我仍在学习使用 rollup 和 typescript 进行构建的细节，所以我无法判断我是否只是做错了什么，或者 @emotion 库是否存在实际问题。

我尝试过设置:

commonjs({
    include: ['/node_modules/**', '../../../node_modules/**'],
    namedExports: {
        'node_modules/@emotion/memoize/dist/memoize.cjs.js': ['memoize']
    }
})

和

commonjs({
    include: ['/node_modules/**', '../../../node_modules/**'],
    namedExports: {
        'node_modules/@emotion/memoize/dist/memoize.cjs.js': ['default']
    }
})

但两者都不起作用。 我尝试安装不同版本的@emotions，从10.0.0到10.0.10，所有版本都会发生这种情况。 我也尝试过直接安装@emotion/memoize，但也不起作用。

这是我的build设置和代码:

自定义按钮.tsx

import React from 'react';
import CustomButtonProps from './custom-button-props';
import styled, { StyledComponent } from '@emotion/styled';
import { StyleConstants } from '@enterprise-api/constants';

export class CustomButton extends React.PureComponent<CustomButtonProps> {
    public constructor(props: CustomButtonProps) {
        super(props);
    }

    private DefaultButton: StyledComponent<any, any, any> = styled.button`
        height: 2rem;
        padding-left: 0.75rem;
        padding-right: 0.75rem;
        ${StyleConstants.defaultButton}
    `;

    public render(): React.ReactNode {
        if (this.props.style) {
            return (
                <button style={this.props.style} onClick={this.props.onClick}>
                    {this.props.text}
                </button>
            );
        }
        return <this.DefaultButton onClick={this.props.onClick}>{this.props.text}</this.DefaultButton>;
    }
}

export default CustomButton;

自定义按钮props.tsx

import { MouseEvent, KeyboardEvent, CSSProperties } from 'react';

export interface CustomButtonProps {
    text: string;
    onClick: (event: MouseEvent | KeyboardEvent) => void;
    style?: CSSProperties;
}

export default CustomButtonProps;

rollup.config.js

import typescript from 'rollup-plugin-typescript2';

    output: [

            file: pkg.main,
            format: 'cjs',
            exports: 'named'
        },
        {
            file: pkg.module,
            format: 'es',
            compact: true
        }
    ],
    external: [...Object.keys(pkg.peerDependencies || {})],

    plugins: [
        typescript({
            typescript: require('typescript')
        }),
        resolve(),
        commonjs({
            include: ['/node_modules/**', '../../../node_modules/**']
        })
    ]
};

我应该能够毫无问题地构建这个组件，但我却收到了上面的错误。

谢谢!

尝试下面的方法，希望它会起作用

commonjs({
  include: 'node_modules/**',
  namedExports: {
    'node_modules/@emotion/memoize/dist/memoize.cjs.js': ['memoize']
  }
}),
