汇总错误:node_modules/react-is/index.js 未导出“isValidElementType" [英] Rollup Error: 'isValidElementType' is not exported by node_modules/react-is/index.js

问题描述

我正在使用 styled-components 构建一个带有 rollUp 的包.

I'm building a bundle with rollUp using styled-components.

我的 rollup.config.js 看起来像:

My rollup.config.js looks like:

import resolve from 'rollup-plugin-node-resolve'
import babel from 'rollup-plugin-babel'
import commonjs from 'rollup-plugin-commonjs'
export default {
  input: 'src/index.js',
  output: {
    file: 'dist/bundle.js',
    format: 'cjs'
  },
  external: [
    'react',
    'react-proptypes'
  ],
  plugins: [
    resolve({
      extensions: [ '.js', '.json', '.jsx' ]
    }),
    commonjs({
      include: 'node_modules/**'
    }),
    babel({
      exclude: 'node_modules/**'
    })
  ]
}

我收到了

[!] Error: 'isValidElementType' is not exported by node_modules/react-is/index.js
https://github.com/rollup/rollup/wiki/Troubleshooting#name-is-not-exported-by-module
node_modules/styled-components/dist/styled-components.es.js (7:9)
5: import stream from 'stream';
6: import PropTypes from 'prop-types';
7: import { isValidElementType } from 'react-is';
            ^
8: import hoistStatics from 'hoist-non-react-statics';

检查 node_modules 本身 react-is 是一个 commonjs 模块，因为它可以检查 这里也是.

Checking on the node_modules itself react-is is a commonjs module as it can be checked out here as well.

commonjs 插件不应该处理它，因为它在 node_modules/** 内部吗?

Shouldn't the commonjs plugin take care of it since it is inside node_modules/** ?

谢谢.

推荐答案

我使用 rollup-plugin-commonjs

并在汇总配置中手动定义导出，如下所示

and defining the export manually in the rollup config as below

export default {
  input: 'src/index.js',
  output: [
    {
      file: pkg.main,
      format: 'cjs',
      sourcemap: true
    },
    {
      file: pkg.module,
      format: 'es',
      sourcemap: true
    }
  ],
  plugins: [
    external(),
    postcss({
      modules: true
    }),
    url(),
    babel({
      exclude: 'node_modules/**'
    }),
    resolve(),
    commonjs({
      include: 'node_modules/**',
      namedExports: {
        'node_modules/react-is/index.js': ['isValidElementType']
      }
    })
  ]
}

此后一切正常.

关于信息，我的初始设置是通过 https://github.com/transitive-bullshit/react-modern-library-boilerplate
