<pre>
import React, { PureComponent } from 'react';
import PropTypes from 'prop-types';
import CSSTransitionGroup from 'react-transition-group';

export default class SimpleAnimation extends PureComponent {
    render() {
        const {children, transitionName, ...props} = this.props;
        const transitions = {
            enter: `${transitionName}-entering`,
            enterActive: `${transitionName}-entered`,
            leave: `${transitionName}-leaving`,
            leaveActive: `${transitionName}-left`,
            appear: `${transitionName}-entering`,
            appearActive: `${transitionName}-entered`
        };

        return (
            <CSSTransitionGroup {...props} transitionName={transitions}>
                {children}
            </CSSTransitionGroup>
        );
    }
}

SimpleAnimation.defaultProps = {
    className: '',
    transitionName: 'component',
    transitionAppear: true,
    transitionEnter: true,
    transitionLeave: true,
    transitionAppearTimeout: 500,
    transitionEnterTimeout: 500,
    transitionLeaveTimeout: 500
};

SimpleAnimation.PropTypes = {
    className: PropTypes.string,
    transitionName: PropTypes.string,
    transitionAppear: PropTypes.bool,
    transitionEnter: PropTypes.bool,
    transitionLeave: PropTypes.bool,
    transitionAppearTimeout: PropTypes.number,
    transitionEnterTimeout: PropTypes.number,
    transitionLeaveTimeout: PropTypes.number
};

这是我们的package.json和一段代码。我试过以下命令：        npm install --save prop-types 但我仍然得到同样的错误：

  

未捕获的TypeError：无法读取属性＆＃39; bool＆＃39;未定义的

我还清理了npm缓存和npm run build命令。 提前谢谢。

我写了console.log（PropTypes），看起来我应该使用checkPropTypes（）

Answer 1

我认为它应该是SimpleAnimation.propTypes而不是PropTypes，因为这是these docs中使用的内容。

Answer 2

我降级了以下依赖关系＆＃39;版本从16.3.1到15.4.0已经修复。

"react": "15.4.0",
"react-dom": "15.4.0",
"react-test-renderer": "15.4.0"
