我有这个简单的代码：
class App extends Component {
render() {
return (
<div>
<PanelPayment />
</div>
);
}
}
export default App
和这个：
export default class PanelPayment {
render() {
return (
<div>
<button>Pay now!</button>
</div>
)
}
}
而且我得到错误：
TypeError：无法将类作为函数调用

请让我知道我在做什么错。
最佳答案
您忘了将其扩展为React.Component类：
export default class PanelPayment extends Component{
render() {
return (
<div>
<button>Pay now!</button>
</div>
)
}
}
