The development server returned response error code: 500 in react native

Question

I am using react-native framework for developing my android app. I want to use react-native-material-design library for making Toolbar wit

Answer 1

As a newcomer to the React-native field, I used to face this error loads of times, and I always used to go confused. After a bit of experience though, I realized, it happens when the server tries to import something from a place which doesn't exist.

So checking what all you are importing and if that thing even exists, must be where you should start.

That means this error doesn't just pop up for an uninstalled package or so, but even if you are importing the wrong thing or from the wrong place.
