React Native PropTypes 已移至单独的包 [英] React Native PropTypes has been moved to a separate package

问题描述

我正在使用

react-native-cli 2.0.1

反应原生 0.47.1

反应 16.0.0-beta.2

我完全是 react-native 的初学者，我决定尝试一下这篇文章中由 Denislav Ganchev 编写的 Employee 应用程序

我看到上面截图中错误中的链接指向迁移，但作为一个完整的初学者，我很难弄清楚我需要做什么.

解决方案

这基本上意味着您需要单独安装该模块，尽管它在以前的版本中是 React 核心模块的一部分.

npm install --save prop-types从 'prop-types' 导入 PropTypes；

更多信息这里

//直到 15.4import React, { PropTypes } from 'react';...React.PropTypes.string.isRequired//现在从反应"导入反应；从 'prop-types' 导入 PropTypes；...PropTypes.string.isRequired

I am using

react-native-cli 2.0.1

react-native 0.47.1

react 16.0.0-beta.2

I am a total beginner in react-native and I decided to give it a try to Employee app written by Denislav Ganchev from this article https://mentormate.com/blog/react-native-components/.

But I am getting this error

Warning: PropTypes has been moved to a separate package. Accessing React.PropTypes is no longer supported and will be removed completely in React 16. Use the prop-types package on npm instead. 

Here is the screenshot of the same error

I see the link in the error in screenshot above pointing to migration but as a complete beginner, I have difficult time figuring what I need to do.

解决方案

It basically means you need to install the module separately, although it was part of React core module in previous versions.

npm install --save prop-types

import PropTypes from 'prop-types';

more info here

// Until 15.4
import React, { PropTypes } from 'react';
...
React.PropTypes.string.isRequired

// Now
import React from 'react';
import PropTypes from 'prop-types';
...
PropTypes.string.isRequired
