错误:提供的对象是`children`，而不是组件、字符串或数字(或它们的列表)

const children = { name: 'John', age: 25 };

function MyComponent() {
  return (
    <div>
      {children}
    </div>
  );
}

const children = 'John';

function MyComponent() {
  return (
    <div>
      {children}
    </div>
  );
}

const children = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 }
];

function MyComponent() {
  return (
    <div>
      {children}
    </div>
  );
}

const children = [
  <ChildComponent name="John" age={25} />,
  <ChildComponent name="Jane" age={30} />
];

function MyComponent() {
  return (
    <div>
      {children}
    </div>
  );
}
