Getting this error while trying to build: Module not found: Error: Can't resolve 'crypto' in

Question

Module not found: Error: Can't resolve 'crypto' in 'C:\Users\Dana\Desktop\myapp\node_modules\web3-eth-accounts\lib' BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to: - add a fallback 'resolve.fallback: { "crypto": require.resolve("crypto-browserify") }'
- install 'crypto-browserify' If you don't want to include a polyfill, you can use an empty module like this: resolve.fallback: { "crypto": false }"

please advise

You have a require('crypto') (or maybe import from 'crypto) in your code.

crypto is a built-in Node.js extension and you are trying to build a browser project.

If that is what you need, as the webpack error message says, you should install a polyfill that implements crypto for the browser.
