Webpack - Error: Cannot find module 'node:assert'

Question

Webpack - Error: Cannot find module 'node:assert'

I tried adding "assert" npm package no luck, any one have any ideas on what is throwing the error?

Are you sure you were trying to install the 'assert' package? (e.g npm install assert) Cause I see you have an error regarding the node:assert package. If it does not work try updating the webpack.config.js and include the assert in the fallback section (this applies to webpack 5) – Leesa

yeah, i tracked down the issue to a build env conflict with netlify plugin that was manifesting this error, ty! – Turnover

Answer 1

Please update node.js to latest versions and that should fix the issue for NX projects

updated node.js to 16.16.0 and this fixed the issue for me. thanks – Ivory

Spot on here 16.16.0 worked for me too, It's a shame that the errors aren't so intuitive. – Clarey

Answer 2

Another thing is if you are using typescript like me, then:

npm i @types/node

And make sure the the tsconfig.json doesn't have a custom typeRoots property that ignores the default types in the node_modules folder

that was my issue, bumped version from v12 to v14 and later to v16 – Cleavable

Answer 3

It occurs when you have an old Node version on your system and a new package is being used in your project, and you receive this error during the compilation process.

Below Solution works for me:

Step: 1 - Uninstall nodejs older version

Step: 2 - Install new version of nodejs. (https://nodejs.org/en/download)

Step: 3 - Remove node_module from the current project

Step: 4 - Run npm i and re-compile your project again

Answer 4

I had the same issue on my macOS Monterey (Apple M1), I tried updating node, using npm & homebrew

• updating with npm didn't work
• updating with homebrew showed an updated status, but when I checked via intellij terminal (node -v) it still returned the old version.

Resolved by running "nvm install node" within intellij's terminal in the project directory.

rm -rf node_modules
rm package-lock.json
npm cache clean --force
npm install
