无法解析模块“反应导航" [英] Unable to resolve module 'react-navigation'

问题描述

这是我得到的错误:

package.json

{
  "name": "LoginApp2",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.0.0-alpha.12",
    "react-native": "0.48.3"
  },
  "devDependencies": {
    "babel-jest": "21.2.0",
    "babel-preset-react-native": "4.0.0",
    "jest": "21.2.1",
    "react-test-renderer": "16.0.0-alpha.12"
  },
  "jest": {
    "preset": "react-native"
  }
}

index.js

  import React, { Component } from 'react';
import { AppRegistry,View,Text,StyleSheet } from 'react-native';

import UsersManager from './pages/app';
AppRegistry.registerComponent('LoginApp2', () => UsersManager);

pages/app.js

import React, { Component } from 'react';
import { AppRegistry,View,Text,StyleSheet,ScrollView,TouchableOpacity } from 'react-native';
import { StackNavigator } from 'react-navigation';

import HomeScreen from './home';
import Login from './login';
import Register from './register';
import Profile from './profile';

const UsersManager = StackNavigator({
Home: { screen: HomeScreen },
Login: { screen: Login },
Register: {screen: Register},
Profile: {screen: Profile}

});
export default UsersManager;

有人可以帮我解决这个问题吗?

Can someone please help me solve this issue?

推荐答案

这个错误意味着你没有安装 react-navigation 模块或者你已经安装了该模块但没有安装使用 react-native run-android 或 react-native run-ios 重新构建你的项目.

This error means that either you haven't installed the react-navigation module or that you have installed the module but didn't re-built your project using react-native run-android or react-native run-ios.

按照以下步骤应该可以解决您的问题:

1. 安装 react-navigation 模块.
2. 重新构建您的项目.
3. 通过停止当前打包程序重新启动打包程序，然后使用 react-native start 再次启动打包器.

1. Install react-navigation module.
2. Re-build your project.
3. Restart the packager by stopping the current packager and then starting the packager again with react-native start.
