Add Favicon with React and Webpack – Twitter API

I am attempting to add a favicon to a React-based website that I made using webpack. It has been a total nightmare to add a favicon and I have tried many solutions to no avail. The latest solution that has been recommended to me is called ‘favicons-webpack-plugin’ which can be found here: https://github.com/jantimon/favicons-webpack-plugin.

If anyone can tell me what I am doing wrong, your assistance would be greatly appreciated.

I get the following error when I run ‘npm run start’

This is my directory structure:

This is my webpack.config.js file:
