Answer 1

import React, { Component, PropTypes } from 'react';
import {
  StyleSheet,
  Text,
  TouchableOpacity,
  View
} from 'react-native';

Including PropTypes next to component helped me

Answer 2

like this : import PropTypes from 'prop-types';

注：reactVersion：0.51

Answer 3

try running

npm outdated

and update the third-party modules that are not at the current version.

I had to do the same after upgrading React Native and uninstall and re-install some modules.

Answer 4

node-modules->react-native-prompt->propmt.js

old : import React, { Component,PropTypes } from 'react';

new:------

import PropTypes from "prop-types" import React, { Component, } from 'react';
