`npm start` got a massive number of error messages

Question

I am setting up the Saleor storefront following this document. However, after calling the command npm start on Windows CMD, there were a massive number of error messages popped up.

I am new to npm and unsure if I missed anything in the configuration.

Please let me know if you need more information. Any hints will be highly appreciated.

You may want to look at the program:
