The console outputs Ignored an update to unaccepted module error, how to fix it?

log.js:25 Ignored an update to unaccepted module ./src/print.js -> 1
log.js:25 [HMR] The following modules couldn't be hot updated: (They would need a full reload!)
log.js:25 [HMR]  - ./src/print.js

the whole console message is:

The following is my code:

webpack.config.js:

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const webpack = require('webpack');

module.exports = {
  devtool: 'inline-source-map',
  devServer: {
    contentBase: path.resolve(__dirname, 'dist'),
    hotOnly: true,
  },
  entry: {
    app: './src/index.js',
    print: './src/print.js'
  },
  output: {
    filename: '[name].bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  plugins: [
    new HtmlWebpackPlugin({
      title: 'Hot Module Replacement',
      filename: 'index.html',
    }),
    new CleanWebpackPlugin(['dist']),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NamedModulesPlugin(),
  ],
};

./src/index.js:

import _ from 'lodash';
import printMe from './print.js';

if(module.hot) {
  module.hot.accept('./print.js', function() {
    console.log('Accepting the updated printMe module!');

    document.body.removeChild(element);
    element = component();
    document.body.appendChild(element);
  });
}

let element = component();

function component() {
  const element = document.createElement('div');
  const btn = document.createElement('button');

  element.innerHTML = _.join(['Hell', 'webpack'], ' ');

  btn.innerHTML = 'Click me and check the console!';
  btn.onclick = printMe;

  element.appendChild(btn);

  return element;
}

document.body.appendChild(element);

./src/print.js:

export default function printMe() {
  //console.log('I get called from print.js!');
  console.log('Updating print.js...')
}
