Same here, tried on two systems.

Hey, I got rid of this error by downgrading my nodejs to v14.21.0 (nodejs-lts-fermium).

Node.js v18.12.1

I downgrade my nodejs to the LTS v16.18.1 (Gallium) to get rid of this error.

[pythagorean]

Add to webpack.config.js:

const crypto = require("crypto");
const crypto_orig_createHash = crypto.createHash;
crypto.createHash = algorithm => crypto_orig_createHash(algorithm == "md4" ? "sha256" : algorithm);

This should fix the error.

[glennDittmann]

@pythagorean Thanks ! Can confirm it worked. I think this should be added to the wasm-book.

[pati08]

Is this an issue with the book, or is this something that should be changed in the template?
