To Reproduce

Steps to reproduce the behaviour:

1. Install https://www.npmjs.com/package/create-react-library
2. npx create-react-library custom-editor
3. cd ustom-editor
4. npm i @toast-ui/editor-plugin-chart @toast-ui/editor-plugin-code-syntax-highlight @toast-ui/editor-plugin-color-syntax @toast-ui/editor-plugin-table-merged-cell @toast-ui/editor-plugin-uml @toast-ui/react-editor katex mermaid --save-dev
5. npm start
6. custom-editor/index.js

import React from 'react'
import { Editor } from '@toast-ui/react-editor'

export default function EditorComponent() {
  return (
    <Editor
      initialValue='hello react editor world!'
      previewStyle='vertical'
      height='600px'
      initialEditType='markdown'
      useCommandShortcut
    />
  )
}

When I did the above-mentioned steps, I started getting the below error.

(commonjs plugin) Error: Custom named exports were specified for /home/rahul/Desktop/projects/temp/editor/tui/node_modules/@toast-ui/editor/dist/esm/index.js but it does not appear to be a CommonJS module

When I saw the content of @toast-ui/editor/dist/esm/index.js then I found below code

export { ToastUIEditor as Editor, ToastUIEditorCore as EditorCore, ToastUIEditor as default };

Start commend in package.json

"start": "microbundle-crl watch --no-compress --format modern,cjs"

How can I solve this problem?

Thanks in advance
