I really wished freecodecamp help you in installing react and node and everything but i guess it makes since because versions are always updating.

In this challenge i try to replicate it in visual code but in the code

Camper.propTypes = {  
name: Proptypes.string.isRequired  
};

PropTypes is not defined and I get a failed to compile. I check on the web and tried to install or import PropTypes but I’m having no luck. How am I suppose to use this on my own?

Just to make sure, It is PropTypes, not Proptypes (capital letter T on type).

```auto
Camper.propTypes = {
name: PropTypes.string.isRequired
};

```

Otherwise:

What is your build tooling, [create-react-app](https://reactjs.org/docs/create-a-new-react-app.html)? If not i would suggest using it, it’s a pretty good way to get started.

You should be able to just npm install prop-types and then import PropTypes from ‘prop-types’

1. Is prop-types in your package.json under the dependencies?
2. Are you importing prop-types into the file you are using it in?

Yeah you’ll need to import it like lasjorg said. It used to be included in the main react package but was seperated into a separate package because lots of people use other typechecking solutions like flow or typescript.
