RollupError：“default”未由“node_modules/react/index.js”导出

Question

第一次使用Rollup创建库，有一个基本的按钮组件，运行时遇到这个错误

rollup - c

src/index.ts → dist/esm/index.js... [!] RollupError：“default”不是由“node_modules/react/index.js”导出，而是由“src/components/Button/Button.tsx”导入。 https://rollupjs.org/troubleshooting/#error-name-is-not-exported-by-module src/components/Button/Button.tsx (1:7) 1：从“react”导入React； ^ 2: const Button = (props) => {

按照故障排除链接中的说明进行操作，安装了

@rollup/plugin-commonjs

但仍然出现此错误。

package.json

{
  "name": "button-library",
  "version": "1.0.0",
  "description": "",

    "rollup": "rollup -c"
  },

汇总配置

import resolve from "@rollup/plugin-node-resolve";
import typescript from "@rollup/plugin-typescript";
import commonjs from "@rollup/plugin-commonjs";
import postcss from "rollup-plugin-postcss";
import dts from "rollup-plugin-dts";

import packageJson from "./package.json" assert { type: "json" };

export default [
  {
    input: "src/index.ts",
    output: [
      {
        dir: "output",
        format: "cjs",
        file: packageJson.module,
        format: "esm",
        sourcemap: true,
      },
    ],
    plugins: [
      resolve(),
      typescript({ tsconfig: "./tsconfig.json" }),
      postcss(),
    ],
  },
  {
    input: "dist/esm/types/index.d.ts",
    output: [
      {
        file: "build/scripts.js",
        format: "esm",
        sourcemap: true,
        globals: ["react"],
      },
      {
        file: "dist/index.d.ts",
        format: "esm",
      },
    ],
    plugins: [
      commonjs({
        include: "./node_modules/**",
      }),
      dts(),
    ],
    external: [/\.(css|less|scss)$/],
  },
];

按钮组件

import React from "react";

interface ButtonProps {
  label: string;
}

const Button = (props: ButtonProps) => {
  return <button>{props.label}</button>;
};

export default Button;

这是有效的配置，还需要更新 tsconfig 并添加 bablerc

import babel from 'rollup-plugin-babel';
import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';
import peerDepsExternal from 'rollup-plugin-peer-deps-external';
import postcss from 'rollup-plugin-postcss';
import typescript from '@rollup/plugin-typescript';

export default {
    input: 'src/index.ts',
    output: [
        {
            file: 'dist/index.js',
            format: 'cjs',
            sourcemap: true
        },
        {
            file: 'dist/index.esm.js',
            format: 'esm',
            sourcemap: true
        }
    ],
    plugins: [
        peerDepsExternal(),
        postcss({
            inject: true
        }),
        typescript(),
        babel({
            extensions: ['.js', '.jsx', '.ts', '.tsx'],
            exclude: 'node_modules/**'
        }),
        resolve(),
        commonjs()
    ],
};

tsconfig

  "compilerOptions": {
    "outDir": "./dist",
    "module": "es6",

      "dom"
    ],
    "sourceMap": true,
    "allowJs": false,
    "jsx": "react",
    "moduleResolution": "node",
    "rootDirs": [

    ],
    "baseUrl": ".",
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "declaration": true
  },
  "include": [
