产生"Functions are not valid as a React child. This may happen if you return a Component instead of <Component /> from render."错误，通常是因为以下两个原因：

  1. 从render中返回一个函数引用而不是一个组件。
  2. 使用 react router 路由作为<Route path="/about" element={About} /> ，而不是<Route path="/about" element={<About />} /> 。

这里有个例子来展示错误是如何发生的。

代码语言：javascript复制
// App.js
/**
 * ⛔️ Functions are not valid as a React child.
 * This may happen if you return a Component instead of <Component /> from render.
 *  Or maybe you meant to call this function rather than return it.
 */
const App = () => {
  const getButton = () => {
    return <button>Click</button>;
  };
