与 TypeScript 反应：类型“{}”不可分配给类型

Question

我在 React 中有一个组件，它显示基于 prop 的导航。当我尝试运行应用程序时，我无法弄清楚为什么会出现此错误：

(19,8): Type '{}' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<TableSystems> & Readonly<{ children?: ReactNode; }...'.
  Type '{}' is not assignable to type 'Readonly<{ todos: any; showNav: boolean; }>'.
    Property 'todos' is missing in type '{}'.

我的组件看起来像这样：

import * as React from 'react'
import Navigation from '../components/Navigation'
import TableSystems from '../components/TableSystems'

class SystemTable extends React.PureComponent<{showNav: boolean }> {
  render(){
  return (

    <div >
    <div >
    <div className="navigationContainer">
    <Navigation {...this.props.showNav} className="sideMenu"/>
      <TableSystems/>
      </div>
    </div>
  </div>)
  }
}


export default SystemTable

我找不到这里有什么问题。

该组件如下所示：

import * as React from 'react';
import history from '../history';


class Navigation extends React.Component<any>  {

constructor(props){
    super(props);
    this.toVersions = this.toVersions.bind(this);
  }

  toVersions(){
    history.push('/versions');
  }

  render() {
    var style = this.props.visible ? "toggled" : "";
    console.log(style);
    return (
      <div className={style} id="wrapper">


        <div id="sidebar-wrapper">
          <ul className="sidebar-nav">
            <li className="sidebar-brand">
              <a href="#">
                Menu
              </a>
            </li>
            <li >
              <a className="nav-link" href="#">List1</a>
            </li>
            <li >
              <a className="nav-link" href="#">List2</a>
            </li>
            <li >
              <a className="nav-link" href="" onClick={this.toVersions}>List3</a>
            </li>
            <li >
              <a className="nav-link" href="#">List4</a>
            </li>
          </ul>
        </div>
      </div>
    )
  }
}

export default Navigation

所以解决方案是将 {...this.props} 添加到组件中，如下所示：

<TableSystems {...this.props}/>
