我是 React 的初学者，我尝试从 FreeCodeCamp 做一个“露营者排行榜”项目。在 StackOverflow 代码片段中，它抛出了我：
` "message": "SyntaxError: Inline Babel script: Expected相应的 JSX 结束标记 for Please help me to find what is wrong. Here's the code:
"use strict";
class TableBox extends React.Component {
constructor(props) {
super(props);

};
}
loadCampersFromServer() {
fetch('https://fcctop100.herokuapp.com/api/fccusers/top/alltime')//alltime or recent
.then(
(response) => {
if (response.status !== 200) {
console.log('Looks like there was a problem. Status Code: ${response.status}');
return;
}
response.json().then((data) => {
console.log('getting data:', data);
this.setState({data: data});
})
}
)
.catch(function (err) {
console.log('Fetch Error :-S', err);
});
}
componentDidMount() {
this.loadCampersFromServer();
}
render() {
return <CampersList />;
}
}
class CampersList extends React.Component {

console.log(this.state);
let campersNodes = this.state.data.map((element, index) => {
return (
<Camper user={element} index={index} />

});
return (
