问在react应用程序中的Usinf pandoc

EN

import './App.css';
import nodePandoc from 'node-pandoc';

let src = './TEST.docx';
 
// Arguments can be either a single String or in an Array
let args = '-f docx -t markdown -o ./markdown.md';
 
// Set your callback function
const callback = (err, result)=> {
 
  if (err) console.error('Oh Nos: ',err)
  return console.log(result), result
}
 
// Call pandoc
nodePandoc(src, args, callback);

function App() {


  return (
    <div className="App">
      <h1> .....</h1>
    </div>
  );
}

export default App;
´´´
However I get this errors: 

ERROR in ../../../../node_modules/node-pandoc/index.js 1:11-29
Module not found: Error: Can't resolve 'fs' in 'C:\Users\apinto2\node_modules\node-pandoc'
