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 native 应用程序中。

我已经将我的 index.js 组件包装在<Provider>每个文档中，但似乎 react-redux 正在搜索一个名为 'src/redux' 的位置，这会引发错误。

我最初尝试在“src/redux”文件夹中组合所有 redux 功能，并使用 jsonconfig.json 将“_redux”别名为路径“src/redux”，子文件夹和 index.js 文件指向子文件夹“actions”、“reducers”和“商店”。

我遇到了一些错误，并认为拥有一个名为“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。

我已经删除了 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，最后通过将 git 重置为 HEAD 并再次添加 appRedux 和新模块从头开始，只是遇到同样的错误。现在我猜可能文件夹命名问题只是一个巧合，但我不知道如何解决。

任何指针？带有 react native 的 redux-toolkit 上没有太多东西，我不想写所有的样板 redux 代码。

完整错误：

Ciao，<Provider>包装器必须用于位于根文件夹的 index.js 文件中。这里有一个例子：

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);
