我正在使用React和Typescript。我有一个充当包装器的react组件，我希望将其属性复制到其子级。我正在遵循React的使用克隆元素的指南：https
:
//facebook.github.io/react/blog/2015/03/03/react-v0.13-rc2.html#react.cloneelement。但是使用时，React.cloneElement我从打字稿中得到以下错误：

Argument of type 'ReactChild' is not assignable to parameter of type 'ReactElement<any>'.at line 27 col 39
  Type 'string' is not assignable to type 'ReactElement<any>'.

如何分配正确的类型给react.cloneElement？

这是一个复制上述错误的示例：

import * as React from 'react';

interface AnimationProperties {
    width: number;
    height: number;
}

/**
 * the svg html element which serves as a wrapper for the entire animation
 */
export class Animation extends React.Component<AnimationProperties, undefined>{

    /**
     * render all children with properties from parent
     *
     * @return {React.ReactNode} react children
     */
    renderChildren(): React.ReactNode {
        return React.Children.map(this.props.children, (child) => {
            return React.cloneElement(child, { // <-- line that is causing error
                width: this.props.width,
                height: this.props.height
            });
        });
    }

    /**
     * render method for react component
     */
    render() {
        return React.createElement('svg', {
            width: this.props.width,
            height: this.props.height
        }, this.renderChildren());
    }
}
