无法从 `node_modules/react-redux/lib/connect/mapDispatchToProps.js 解析模块 `../../../../src/redux`

Question

我第一次尝试原子设计时，正在尝试将带有 redux 工具包的 redux 添加到现有的 React 本机应用程序中。

我根据文档将我的 index.js 组件包装在 <Provider> 中，但似乎 react-redux 正在搜索一个名为 'src/redux' 的位置，这会引发错误。

我最初尝试将所有 redux 功能组合在一个 'src/redux' 文件夹中，并使用 jsonconfig.json 将“_redux”别名为路径 'src/redux' 与子文件夹和 index.js 文件指向到子文件夹 'actions'、'reducers' 和 'store'.

我遇到了一些错误，并认为有一个名为 'redux' 的文件夹可能是错误的形式，所以我将其更改为 'appRedux' 然后出现了这个问题。

我已经删除 node_modules 并重新安装了多次，清除了 metro 缓存，在整个应用程序中搜索了对 'src/redux' 的任何引用，最后通过重置 git 从头开始到 HEAD 并再次添加 appRedux 和新模块，只会遇到同样的错误。现在我猜测也许文件夹命名问题只是巧合，但我不知道如何解决。

有什么指点吗？ redux-toolkit 上没有太多的 react native，我不想写所有的样板 redux 代码。

完全错误：

再见，<Provider> 包装器必须用于根文件夹中的 index.js 文件。举个例子：

index.js

import React from 'react';
import { AppRegistry } from 'react-native';
import App from './App';
import { name as appName } from './app.json';
import { Provider } from 'react-redux';
import { store } from "./app/redux/store";


const ReduxApp = () => (
    <Provider store={store}>
        <App />
    </Provider>
 )

 AppRegistry.registerComponent(appName, () => ReduxApp);
