调度员为空

Question

调度员为空 我遇到此错误任何人都可以帮助我如何解决它 错误

我尝试了很多方法但无法解决这个问题

调度员为空

当我尝试使用 useDispatch 挂钩时，我似乎收到一条错误消息“调度程序为空”。我怀疑问题出在这个组件上。请参阅屏幕截图以获取详细的错误信息。

import React, { useEffect, useState } from 'react'
import { Button } from 'antd';
import './Product.css'
import { useDispatch } from 'react-redux';
import { add } from '../Store/Slices/cartSlice';
function Product() {
const \[products, setProducts\] = useState(\[\]);
useEffect(() =\> {
const  fetchApi = async () =\> {
const dataApi = await fetch('https://fakestoreapi.com/products');
const data = await dataApi.json();
setProducts(data);
}
fetchApi();
},\[\]);

    const dispatch = useDispatch();
    
    function handleAdd(product){
      dispatch(add(product));
    }

return (
\<div className='productWrapper'\>

{
products.map((product) =\> (
\<div className='card' key ={product.id}\>
\<img src={product.image} style={{width:"80px"}}/\>
<h4>{product.title}</h4>
<h5>{product.price}</h5>
\<Button type="primary" onClick={handleAdd(product)}\>Add to Cart\</Button\>
\</div\>

        ))
        }
    </div>

)
}

export default Product

看起来像是某种冲突...您可以尝试清除canche并重新安装吗？

npm cache clean -f
npm i
