javascript - 我收到 TypeError: oacreateRef is not a function in react

Question

我正在尝试在我的React项目中添加一个开源编辑器。我使用NPM安装了它。为了快速检查它是否已安装，我只是从 npm网站复制粘贴了代码片段。 代码

import React from 'react';
import 'codemirror/lib/codemirror.css';
import '@toast-ui/editor/dist/toastui-editor.css';
 
import { Editor } from '@toast-ui/react-editor';
 
class MyComponent extends React.Component {
  editorRef = React.createRef();
 
  handleClick = () => {
    this.editorRef.current.getInstance().exec('Bold');
  };
 
  render() {
    return (
      <>
        <Editor
          previewStyle="vertical"
          height="400px"
          initialEditType="markdown"
          initialValue="hello"
          ref={this.editorRef}
        />
        <button onClick={this.handleClick}>make bold</button>
      </>
    );
  }
}

错误
