为什么不导出 reduxjs-toolkit 中的操作? (React Js - redux 工具包)

Why actions in reduxjs-toolkit are not exported ? (Reactjs - reduxToolkit)

我正在使用@reduxjs/toolkit 和 reactjs 构建购物车,当我从 Cart.js 导出操作并尝试将它们导入其他文件,如 cart.jsx 和 header.jsx,它说:

点击调用 addToCart 导入操作的 addTocart 按钮后检查 CONSOLE 时,它显示:

这是cart.js(位于redux文件夹)代码:

import { createSlice } from "@reduxjs/toolkit";

export const cartSlice = createSlice({
  name: "cart",
  initialState: {
    cartProds: []
    },
  reducers: {
    addToCart: (state, {payload})=>{
       const exist = state.cartProds.find(prod => prod.id === payload.id);
       if(exist){
            return  state.cartProds.map(prod => prod.id === payload.id ? {...prod, quantity: prod.quantity + 1}: prod);
       }
       if(!exist){
        return  state.cartProds = [...state, {...payload, quantity: 1}];
       }
    },
    removeFromCart :(state, {payload}) =>{
        const exist1 = state.find( prod => prod.id === payload.id);
        if(exist1.quantity === 1){
            return state.filter(prod => prod.id !== exist1.id);
        }else{
            return state.map(prod => prod.id === payload.id ? {...prod, quantity:prod.quantity-1}: prod);
        }
    }
  }
});

export const { addTocart, removeFromCart } = cartSlice.actions;
export default cartSlice.reducer;

这是我导入它们的方式(路径绝对正确!):

import { addToCart, removeFromCart } from '../redux/cart.js';

您已经导出 addTocart(但是在 createSlice -> reducer 中您有 addToCart

export const { addTocart, removeFromCart } = cartSlice.actions;

并导入了addToCart

import { addToCart, removeFromCart } from '../redux/cart.js';

区分大小写!
