javascript - React Navigation - createStackNavigator 错误 - “未定义不是函数”

问题描述

我创建了以下代码以导入 app.js

import React from "react";
import { View } from "react-native";
import { createStackNavigator } from "react-navigation";
import HomeScreen from '../screens/HomeScreen';
import ProfileScreen from '../screens/auth/ProfileScreen';
import FilterScreen from '../screens/FilterScreen';

  const Routes = createStackNavigator(
      {
        Home: {
          screen: HomeScreen
        },
        Filters: {
          screen: FilterScreen
        },
        Profile: {
          screen: ProfileScreen
        }
      },
      {
        initialRouteName: "Home",
        navigationOptions: {
          headerTitleStyle: {
            fontWeight: "bold",
            color: "#fff",
          },
          headerTintColor: "#fff"
        }
      }
    );

    export default Routes;

我正在按如下方式导入 app.js

import Routes from './navigation/StackNavigator';

在此阶段预览我的应用程序时，我收到以下错误：

undefined is not a function (near '...(0, 

_reactNavigation.createStackNavigator)...')

<unknown>
    C:\Apps\test\app\navigation\StackNavigator.js:9:6

有谁知道可能出了什么问题？我要扯头发了！任何建议将不胜感激！

解决方案

建议：

  • 将路线重命名为其他名称，例如Routes1（在两者app.js中navigation/StackNavigator）

  • 缩小错误的范围，例如删除选项createStackNavigator并尝试以下操作：

    const Routes1 = createStackNavigator();

    export default Routes1;

  • 试试这个文件中的选项卡导航器（而不是 stackNavigator），看看它是否工作正常。

  • 清理并强制重新安装模块
