我想在我的 Next.js 应用程序中设置 REdux。但我被卡住了。不知道为什么。一切都与教程中的相同。

计数器.js：

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

export const counterSlice = createSlice({
  name: "counter",
  initialState: {
    count: 0,
  },
  reducers: {
    increment: (state) => {
      // Redux Toolkit allows us to write "mutating" logic in reducers. It
      // doesn't actually mutate the state because it uses the Immer library,
      // which detects changes to a "draft state" and produces a brand new
      // immutable state based off those changes
      state.count += 1;
    },
    decrement: (state) => {
      state.count -= 1;
    },
    incrementByAmount: (state, action) => {
      state.count += action.payload;
    },
  },
});

// Action creators are generated for each case reducer function
export const { increment, decrement, incrementByAmount } = counterSlice.actions;

export default counterSlice.reducer;

商店.tsx：

import { configureStore } from "@reduxjs/toolkit";
import { counterReducer } from "./counter";

export default configureStore({
  reducer: {
    counter: counterReducer,
  },
});

onboarding2.tsx 的第一部分：

import Head from "next/head";
import Image from "next/image";
import React, { useState, useEffect } from "react";
import { useDispatch, useSelector } from "react-redux";

export const fallBackLang = "hu";

interface Onboarding2Props {
  lang: string;
  translations: Translation;
}

export default function Onboarding2(props: Onboarding2Props) {
  const { lang, translations } = props;
  const { count } = useSelector((state) => state.counter);
