Cannot find module 'prettier' - node.js

Question

I updated all packages but still getting this error after running npm run serve:
Module build failed (from ./node_modules/eslint-loader/index.js):
Error: Cannot find module 'prettier' Occurred while linting /home

**"#vue/eslint-config-prettier": "^5.0.0",** is listed in the dependencies. How to fix this issue? (I'm using VSCODE on Ubuntu)
I tried multiple times deleting package-lock.json and node_modules and running npm install afterwards. Nothing fixes it - even updating all packages globally.

Answer 1

Prettier is a peer dependency of
#vue/eslint-config-prettier so you need to add it to your own dependencies:
npm install --save-dev prettier

Answer 2

With NPM
npm install --save-dev prettier
With Yarn
yarn add --dev prettier

Answer 3

if you're using yarn 3, and yarn add --dev prettier doesn't solve your problem, try this:
cmd + shift + p
in the dropdown, search for preferences: open user settings (json)
add "prettier.prettierPath": ".yarn/sdks/prettier/index.js" to your json file.
This tells your editor to find the module in the path you added.
