Question

我有一个旧的React Native项目，现在我想与Expo一起运行它。问题是当我尝试使用Expo打开项目并启动它时，Expo软件停留在“等待程序包和隧道启动”。我正在使用已经安装了watchman的MacOS。

这是我的项目

的结构

我的app.json：

{ "name": "myapp", "displayName": "myApp", "expo": { "sdkVersion": "28.0.0" } }

package.json：

{
  "name": "MyApp",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "expo": "^28.0.0",
    "react": "15.4.1",
    "react-native": "0.42.0",
    "react-native-calendar-strip": "^0.1.4",
    "react-native-check-box": "^1.0.4",
    "react-native-checkbox": "^1.1.0",
    "react-native-code-push": "1.17.0-beta",
    "react-native-collapsible": "0.8.0",
    "react-native-datepicker": "^1.6.0",
    "react-native-fetch-blob": "0.10.6",
    "react-native-image-picker": "0.26.2",
    "react-native-keyboard-aware-scroll-view": "^0.2.9",
    "react-native-modal-picker": "0.0.16",
    "react-native-modalbox": "1.3.9",
    "react-native-pdf": "1.2.4",
    "react-native-picker": "4.0.18",
    "react-native-signature-pad": "git+https://github.com/silverspace/react-native-signature-pad/#greg/android_blank_workaround",
    "react-native-simple-store": "^1.2.0",
    "react-native-vector-icons": "4.0.1",
    "react-navigation": "1.0.0-beta.7",
    "react-redux": "5.0.3",
    "realm": "2.11.0",
    "redux": "3.6.0",
    "redux-logger": "2.8.2",
    "redux-thunk": "2.2.0",
    "tipsi-stripe": "3.2.0"
  },
  "devDependencies": {
    "babel-jest": "19.0.0",
    "babel-preset-react-native": "1.9.1",
    "jest": "20.0.4",
    "react-test-renderer": "15.4.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

index.ios.js和index.android.js具有相同的代码：import'./App';

这是我的App.js：

import React from 'react';
import {
  AppRegistry,
  Text,
  View,
  Button,
  AppState,
  DeviceEventEmitter
} from 'react-native';
import { BackAndroid } from 'react-native'
import { NavigationActions, StackNavigator } from 'react-navigation';
// Redux
import { Provider } from 'react-redux'
import store from './app/store'
import codePush from 'react-native-code-push';
import HomeNavigation from './app/Home/screens/HomeNavigation'
import simpleStore from 'react-native-simple-store';

import { HOST } from './app/Common/constants';
const GET_USER_URL = `${HOST}/api/user`;

let codePushOptions = {
   checkFrequency: codePush.CheckFrequency.ON_APP_RESUME,
   installMode: codePush.InstallMode.ON_NEXT_RESUME
};

class App extends React.Component {

   //Doing something here...

    render(){
        return(
            <Provider store={store}>
                <HomeNavigation />
            </Provider>
        )
    }
}

export default CodePushApp = codePush(codePushOptions)(App);

AppRegistry.registerComponent('MypApp', () => CodePushApp);

我已经尝试在Windows PC上安装Expo，但是尝试运行此项目时仍然遇到相同的问题。

我知道已经晚了，但是如果您已经安装了expo-cli，请尝试将package.json文件的scripts部分更改为以下内容

{{1}}

}

这对我有用

无法通过Expo运行React Native项目
