Cannot find module 'yargs' error #

To solve the error "Cannot find module 'yargs'", make sure to install the yargs package by opening your terminal in your project's root directory and running the following command: npm i yargs. If you use TypeScript, install the typings by running npm i -D @types/yargs.

index.js
// ⛔️ Cannot find module 'yargs' // Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'yargs' // imported from bobbyhadz-js/index.js import yargs from 'yargs'; import {hideBin} from 'yargs/helpers'; yargs(hideBin(process.argv)) .command( 'curl <url>', 'fetch the contents of the URL', () => {}, argv => { console.info(argv); }, ) .demandCommand(1) .parse();

Open your terminal in your project's root directory (where your package.json file is located) and run the following commands:

shell
npm install yargs # 👇️ only if you use TypeScript npm install --save-dev @types/yargs

This will add the yargs package to the dependencies of your project.

If the error is not resolved, try to delete your node_modules and package-lock.json (not package.json) files, re-run npm install and restart your IDE.

shell
# 👇️ delete node_modules and package-lock.json rm -rf node_modules rm -f package-lock.json # 👇️ clean npm cache npm cache clean --force npm install
Make sure to restart your IDE and dev server if the error persists. VSCode often glitches and a reboot solves things sometimes.

If you're still getting the "Cannot find module 'yargs'" error, open your package.json file and make sure it contains the yargs package in the dependencies object.

package.json
{ // ... rest "dependencies": { "yargs": "^17.4.0" }, "devDependencies": { // 👇️ only if you use TypeScript "@types/yargs": "^17.0.10", } }

You can try to manually add the line and re-run npm install.

shell
npm install
