Undefined Is Not An Object (evaluating 'react.proptypes.number') Error

Just updated from expo 21.0.0 to 22.0.0 and I am getting this error: this is my package.json: { 'name': 'APP', 'version': '0.1.0', 'private': true, 'devDependencies': {

Solution 1:

PropTypes is removed from react so you need to install prop-types and import it from that:

Install prop-types:

npm install prop-types --save

Import PropTypes from prop-type instead of import PropTypes from react:

importPropTypesfrom'prop-types';

Solution 2:

Check JS file for all module from npm module

"react-native-autocomplete-input":"3.3.1","react-native-check-box":"2.0.0","react-native-easy-toast":"1.0.9","react-native-elements":"0.13.0","react-native-global-props":"1.1.1","react-native-htmlview":"0.12.1","react-native-modal-dropdown":"0.5.0","react-native-modalbox":"1.4.2","react-native-parallax-scroll-view":"0.20.1","react-native-tag-input":"0.0.14","react-native-vector-icons":"4.2.0","react-navigation":"^1.0.0-beta.27"

replace

import {PropTypes} from'react';

with

importPropTypesfrom'prop-types';

in every file
