Why is the PropTypes detection type of my React component invalid?

import React from "react";
import PropTypes from" prop-types";

/ / < Pt name= {1} / >

export default class Pt extends React.Component {
static propTypes = {

type: PropTypes.string

};

render () {

return (
  <h1> { this.props.name } </h1>
)

};
};
