webpack copy plugin gives error: output.filename is required, either in config file or as --output-filename

As a clean node project I do:

npm install webpack copy-webpack-plugin

and this is my webpack.config.js file:

var CopyWebpackPlugin = require('copy-webpack-plugin');
var path = require('path');

module.exports = {
  plugins: [
    new CopyWebpackPlugin([
      {
        from: 'src',
        to: 'dist'
      }
    ])
  ]
};

when I run npm run webpack get this error message:

$ npm run webpack

                throw new Error("'output.filename' is required, either in config file or as --output-filename");
                ^

Try to add entry and output in webpack.config.js

const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require('path');

const rootPath = path.join(__dirname, '/');

module.exports = {
  entry: {
    main: `${rootPath}/src/main.js`,
  },

  output: {
    filename: '[name].[hash].js',
    path: `${rootPath}/dist`,
  },

  plugins: [
    new CopyWebpackPlugin([
      {
        from: 'src',
        to: 'dist'
      }
    ])
  ]
};

Hope this may help you.
