export default Swimming;

Answer 1

您需要在组件上设置静态属性“propTypes”以满足此 lint 错误。

这里有一些关于 React 的 PropTypes 的信息：React Docs

您将添加一个类似于此的部分：

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

class Swimming extends React.Component {
 static propTypes = {
   jumping: PropTypes.bool,
   playerLaughing: PropTypes.func
 };
 constructor(props) {
 ...
}

您需要安装“prop-types”npm 包。

Answer 2

您应该将propTypes 添加到您的组件中：
例如：

// this goes outside the class deceleration 
Swimming.propTypes = {
    playerLaughing: PropTypes.func,
    jumping: PropTypes.bool,
    //... other props you will use in this component
};  

如果你想在 class 减速中使用它，你可以像这样使用静态类字段：

// this goes inside the class deceleration
static propTypes = {
        playerLaughing: PropTypes.func,
        jumping: PropTypes.bool,
        //... other props you will use in this component
    };
}; 

您应该安装并导入PropTypes。见Docs

npm install --save prop-types
import PropTypes from 'prop-types'; // ES6 
var PropTypes = require('prop-types'); // ES5 with npm
