Question

我在超级（道具）; 上收到错误调用目标不包含任何签名。

有人请解释错误的含义以及解决方法吗？ TY

declare var require: any
var React = require('react');
var ReactDOM = require('react-dom');

class Button extends React.Component {

    constructor(props) {
        super(props);
        this.state = { count: 0 };
    }

    render() {
        return (
            <button> CLICK ME </button>    
        );
    }
}

ReactDOM.render(<Button />, document.getElementById('root'));

替换这段代码：

declare var require: any
var React = require('react');
var ReactDOM = require('react-dom');

... with：

import * as React from "react";
import * as ReactDOM from "react-dom";

您的全部新代码现在将如下所示：

// declare var require: any
// var React = require('react');
// var ReactDOM = require('react-dom');
import * as React from "react";
import * as ReactDOM from "react-dom";

class Button extends React.Component {

  constructor(props) {
    super(props);
    this.state = { count: 0 };
  }

  render() {
    return (
      <button> CLICK ME </button>
    );
  }
}

ReactDOM.render(<Button />, document.getElementById('root'));
