错误:组件列表映射上的钩子调用无效。ReactJS

Question

在中，我希望在下面使用钩子并获得错误。

实际上，我使用YhSection来管理并行组件，并使用数组映射将它们放在布局内容中。

我发现如果我用钩子

{yhSection.map((section) => (
    <Route key={section.key} path={section.path}>
      {section.components}
    </Route>
))}

它起作用了，但在里面，它不起作用。

钩子调用错误在Review.tsx中

我非常感谢你的帮助。

错误:无效钩子调用。钩子只能在函数组件的主体内调用。这种情况的发生有以下原因之一：

1. 您可能有React的不匹配版本和呈现器(例如React )
2. ，您可能正在违反Hooks
3. 的规则，您可能在同一个应用程序

中有多个React副本。

MyContentWithRoute.tsx

import React, { FC } from 'react';
import { Route, Switch } from 'react-router-dom';
import { Layout } from 'antd';
import My404 from './My404';

import yhSection from './YhSection';

const MyContentWithRoute: FC = () => (
  <Layout.Content style={{ margin: '16px', background: '#fff' }}>
    <Switch>
      {yhSection.map((section) => (
        <Route key={section.key} path={section.path}>
          {section.components}
        </Route>
      ))}
      <Route path="*">
        <My404 />
      </Route>
    </Switch>
  </Layout.Content>
);

export default MyContentWithRoute;

Answer 1

似乎您正在尝试呈现一个组件函数，而不是组件JSX实例。看看这个：

{ key: 'review', path: '/review', components: Review }, // here Review is component function

{yhSection.map((section) => (
    <Route key={section.key} path={section.path}>
      {/* here it is still a component function not a JSX element (it is Review and not <Review /> or React.createElement(Review) */}
      {section.components}
    </Route>
))}

尝试将组件函数作为参数直接传递到Route：

{yhSection.map((section) => (
  <Route key={section.key} path={section.path} component={section.components} />
))}

Answer 2

尝试以下几点

<Route 
  key={section.key}
  path={section.path}
  component={section.components} 
/>
