我无法在typescript中使用动态密钥名称setState

import React, { Component } from 'react';

interface MyComponentState {
  [key: string]: any;
}

class MyComponent extends Component<{}, MyComponentState> {
  constructor(props: {}) {
    super(props);
    this.state = {};
  }

  updateState(key: string, value: any) {
    this.setState({ [key]: value });
  }

  render() {
    return (
      <div>
        {/* 在组件中使用状态 */}
      </div>
    );
  }
}
