我在我的 react 应用程序中创建了一个 react-codemirror 2 组件，但包的 linting 功能不起作用。我尝试浏览其他堆栈溢出问题，但由于这些问题至少有 2 年的历史，看起来原始库的文件结构，即 codemirror 已更改，并且似乎没有一个解决方案有效。我还在他们的 Github 存储库中打开了一个问题，但没有对此作出回应。希望您能提供帮助，这是我的组件的代码。

import React from "react";
import { UnControlled as CodeMirror } from "react-codemirror2";

import 'codemirror/lib/codemirror.css';
import 'codemirror/theme/material.css';
import 'codemirror/addon/lint/lint.css';
import 'codemirror/addon/hint/show-hint.css';



import 'codemirror/mode/javascript/javascript.js';
import 'codemirror/addon/lint/javascript-lint';
import 'codemirror/addon/lint/lint.js';
import 'codemirror/addon/hint/javascript-hint';


const JsEditor = ({code}) => {
  return (
    <div>
      <h1> JavaScript </h1>
      <CodeMirror
        value={code}
        options={{
          gutters: ["CodeMirror-lint-markers"],
          mode: "javascript",
          theme: "material",
          lineNumbers: true,
          lineWrapping: true,
          lint: true,
         
        }}
       
      />
    </div>
  );
};

export default JsEditor;

CodeMirror 的 lint 插件需要 jshint 库。如果添加它 ( npm i jshint)，以下代码应该可以工作：

import React from 'react';
import { UnControlled as CodeMirror } from "react-codemirror2";
import 'codemirror/lib/codemirror.css';
import 'codemirror/theme/material.css';
import 'codemirror/addon/lint/lint.css';
import 'codemirror/addon/hint/show-hint.css';
import 'codemirror/mode/javascript/javascript.js';
import 'codemirror/addon/lint/javascript-lint';
import 'codemirror/addon/lint/lint.js';
import 'codemirror/addon/hint/javascript-hint';
import { JSHINT } from 'jshint';
window.JSHINT = JSHINT;

const JsEditor = ({ code }) => {
  return (
    <div>
      <h1> JavaScript </h1>
      <CodeMirror
        value={code}
        options={{
          gutters: ["CodeMirror-lint-markers"],
          mode: "javascript",
          theme: "material",
          lineNumbers: true,
          lineWrapping: true,
          lint: true,
        }}
      />
    </div>
  );
};

function App() {
  return (
    <div className="App">
      <JsEditor code={'var widgets =[]; debugger'} />
    </div>
  );
}

export default App;
