Question

当我尝试通过snack.expo在模拟器或设备上运行app时，我收到此错误：

设备：（741：6637）无法安装模块'project_modules / containers /＆lt;％name％＆gt;'：无法下载模块'project_modules~container~＆lt;％name％＆gt; @latest' 从app.js导入

＆LT;％名称％GT;可以在不同的屏幕之间进行更改，所有这些都来自目录project_modules / containers / 代码：

App.js

import React from 'react';

import { createStackNavigator } from 'react-navigation';
import AuthScreen from 'project_modules/containers/auth_screen'
import SelectProjectScreen from     'project_modules/containers/select_project_screen'
import ProjectScreen from 'project_modules/containers/project_screen'
import SelectTaskScreen from 'project_modules/containers/project_select_task_screen'
import TeamScreen from 'project_modules/containers/project_team_screen'
import CamerasScreen from 'project_modules/containers/project_cameras_screen'
import store from "./project_modules/instances/store";
import {Provider} from "react-redux";
import {INITIAL_PARAMS} from "./project_modules/constants/state_constants/project_constants";

const Root = createStackNavigator({
    SelectProject: {screen: SelectProjectScreen},
    ProjectScreen: {screen: ProjectScreen},
    SelectTaskScreen: {screen: SelectTaskScreen},
    TeamScreen: {screen: TeamScreen},
    CamerasScreen: {screen: CamerasScreen},
    AuthScreen: {screen: AuthScreen}
}, {
    initialRouteName: 'AuthScreen',
    initialRouteParams: INITIAL_PARAMS
});

const App = () => {
    return (
        <Provider store={store}>
            <Root/>
        </Provider>
    )
};

export default App

index.js

import {AppRegistry} from 'react-native';
import App from './App';

AppRegistry.registerComponent('SIBM', () => App);

此问题通过绝对路径打包解决。我在每个大目录中都添加了自己的带有字段“名称”的 package.json 。然后我得到这样的进口：

import AuthScreen from 'containers/auth_screen'

无法安装目录中存在的屏幕模块
