I had this error once while trying to install the npm package react-devtools.

leiluspocus$ npm i -g react-devtools

The issue was that I was previously installing npm packages using the root user.

It’s pretty impressive how we can simply set up a development environment without XCode using Expo.

Make sure you’re using the right Node and NPM versions and double check that there are no missing packages while doing the npm install.

I had to run these commands before running npm start on my app (created through create-react-native-app ):
