Question

I am trying to run a react application in my local machine , I get this error when I ran npm run start:

> node scripts/start.js

internal/validators.js:125
    throw new ERR_INVALID_ARG_TYPE(name, 'string', value);
    ^

npm ERR! code ELIFECYCLE
npm ERR! errno 1

I have tried to do the following but it is the same:

1. npm cache clean --force
2. delete node_modules with package-lock.json
3. npm install

Thanks in advance,

Answer 1

Make sure you have the correct version of react-scripts. Try react-scripts 3.4.0.

If you have a previous version of react-scripts, you can follow the directions on how to migrate from your version to 3.4.0: https://github.com/facebook/create-react-app/releases

Another option is to update your package.json file to use "react-scripts": "3.4.0". Make sure you delete your node_modules folder and package-lock.json before running npm install after updating the package.json

Answer 2

Changing my version of react-scripts from 3.3.1 to 3.4.0 worked for me. Use the command

npm install --save --save-exact [email protected]

If you have [email protected] already you can upgrade it to v3.4.1 with the same command. This automatically updates the version listed on your package.json file.
