javascript - 汇总错误 : 'default' is not exported by node_modules/react/index. js

Question

我有一个项目，我使用 webpack 并想切换到 rollup.js，但我在插件 @rollup/plugin-commonjs 方面遇到了麻烦。
我的 rollup.conf.js

import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
import babel from 'rollup-plugin-babel';
import { terser } from 'rollup-plugin-terser';
import nodePolyfills from 'rollup-plugin-node-polyfills';

const config = {
    input: 'site/templates/scripts/master.js',
    output: [
        {
            file: 'site/templates/scripts/master.min.js',
            format: 'cjs'
        }
    ],
    plugins: [
        nodePolyfills(),
        resolve({
            browser: true
        }),
        commonjs({
            include: /node_modules/,
            namedExports: {
                'react': ["useState", "useEffect"],
                '@apollo/client': ['ApolloProvider', 'ApolloClient', 'HttpLink', 'InMemoryCache', 'useQuery', 'gql'],
                'styled-components': [ 'styled', 'css', 'ThemeProvider' ]
            }
        }),
        babel({
            babelrc: true,
            exclude: 'node_modules/**'
        }),
        terser()
    ]
};

export default config;

我遇到的错误，不知道如何解决

site/templates/scripts/master.js → site/templates/scripts/master.min.js...

https://rollupjs.org/guide/en/#error-name-is-not-exported-by-module page 并没有真正的帮助，因为我已经在我的配置中使用了所有命名的导出。

最后我发现了问题所在。我需要 @rollup/plugin-replace替换插件process.env.NODE_ENV这是工作代码
它还需要更多的命名导出。

import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
import babel from 'rollup-plugin-babel';
import { terser } from 'rollup-plugin-terser';
import nodePolyfills from 'rollup-plugin-node-polyfills';
import replace from '@rollup/plugin-replace';

import React from 'react';
import ReactIs from 'react-is';
import ReactDOM from 'react-dom';

const config = {
    input: 'site/templates/scripts/master.js',
    output: [
        {
            file: 'site/templates/scripts/master.min.js',
            format: 'cjs'
        }
    ],
    plugins: [
        replace({
            "process.env.NODE_ENV": JSON.stringify("development")
        }),
        nodePolyfills(),
        resolve({
            browser: true
        }),
        commonjs({
            include: /node_modules/,
            namedExports: {
                'react-is': Object.keys(ReactIs),
                'react': Object.keys(React),
                'react-dom': Object.keys(ReactDOM),
                '@apollo/client': ['ApolloProvider', 'ApolloClient', 'HttpLink', 'InMemoryCache', 'useQuery', 'gql'],
                'styled-components': [ 'styled', 'css', 'ThemeProvider' ]
            }
        }),
        babel({
            babelrc: true,
            exclude: 'node_modules/**'
        }),
        terser()
    ]
};

export default config;
