getting undefined is not a function (evaluating &#

2020-06-07 03:36发布

In my application I need drawer navigation, for that I am using sample code from this. I have integrated everything in my application, but getting the following error

undefined is not a function (evaluating '(0,_reactNavigation.stacknavigator)')

And installed this one too.

npm install react-navigation --save

But don't know why this error is coming, So please guide me how to resolve this.

This is my app.js

import React, { Component } from 'react';
import { StyleSheet , Platform , View , Text , Image , 
         TouchableOpacity , YellowBox } from 'react-native';
import { DrawerNavigator, StackNavigator } from 'react-navigation';

class NavigationDrawerStructure extends Component {
  //Structure for the navigatin Drawer
  toggleDrawer = () => {
    //Props to open/close the drawer
    this.props.navigationProps.toggleDrawer();
  };
  render() {
    return (
      <View style={{ flexDirection: 'row' }}>
        <TouchableOpacity onPress={this.toggleDrawer.bind(this)}>
          {/*Donute Button Image */}
          <Image
            source={require('./image/drawer.png')}
            style={{ width: 25, height: 25, marginLeft: 5 }}
          />
        </TouchableOpacity>
      </View>
    );
  }
}

class Screen1 extends Component {
  //Screen1 Component
  render() {
    return (
      <View style={styles.MainContainer}>
        <Text style={{ fontSize: 23 }}> Screen 1 </Text>
      </View>
    );
  }
}

class Screen2 extends Component {
  //Screen2 Component
  render() {
    return (
      <View style={styles.MainContainer}>
        <Text style={{ fontSize: 23 }}> Screen 2 </Text>
      </View>
    );
  }
}

class Screen3 extends Component {
  //Screen3 Component
  render() {
    return (
      <View style={styles.MainContainer}>
        <Text style={{ fontSize: 23 }}> Screen 3 </Text>
      </View>
    );
  }
}

const FirstActivity_StackNavigator = StackNavigator({
  //All the screen from the Screen1 will be indexed here 
  First: {
    screen: Screen1,
    navigationOptions: ({ navigation }) => ({
      title: 'Screen1',
      headerLeft: <NavigationDrawerStructure navigationProps={navigation} />,
      headerStyle: {
        backgroundColor: '#FF9800',
      },
      headerTintColor: '#fff',
    }),
  },
});

const Screen2_StackNavigator = StackNavigator({
  //All the screen from the Screen2 will be indexed here
  Second: {
    screen: Screen2,
    navigationOptions: ({ navigation }) => ({
      title: 'Screen2',
      headerLeft: <NavigationDrawerStructure navigationProps={navigation} />,
      headerStyle: {
        backgroundColor: '#FF9800',
      },
      headerTintColor: '#fff',
    }),
  },
});

const Screen3_StackNavigator = StackNavigator({
  //All the screen from the Screen3 will be indexed here
  Third: {
    screen: Screen3,
    navigationOptions: ({ navigation }) => ({
      title: 'Screen3',
      headerLeft: <NavigationDrawerStructure navigationProps={navigation} />,
      headerStyle: {
        backgroundColor: '#FF9800',
      },
      headerTintColor: '#fff',
    }),
  },
});

const DrawerNavigatorExample = DrawerNavigator({
  //Drawer Optons and indexing
  Screen1: { //Title
    screen: FirstActivity_StackNavigator,
  },

  Screen2: {//Title
    screen: Screen2_StackNavigator,
  },

  Screen3: {//Title
    screen: Screen3_StackNavigator,
  },
});
export default DrawerNavigatorExample;

const styles = StyleSheet.create({
  MainContainer: {
    flex: 1,
    paddingTop: 20,
    alignItems: 'center',
    marginTop: 50,
    justifyContent: 'center',
  },
});

And this is package.json

{
  "name": "DrawerNavigation",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.6.1",
    "react-native": "0.57.5",
    "react-native-vector-icons": "^6.1.0",
    "react-navigation": "^3.0.0"
  },
  "devDependencies": {
    "babel-jest": "23.6.0",
    "jest": "23.6.0",
    "metro-react-native-babel-preset": "0.49.2",
    "react-test-renderer": "16.6.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

you could have a look at this example code here: https://snack.expo.io/@eriveltonelias/stack-actions

I think the problem is :

  1. with stackNavigator, you should use createStackNavigator (https://reactnavigation.org/docs/en/stack-navigator.html) and
  2. instead of drawerNavigator use createDrawerNavigator (https://reactnavigation.org/docs/en/drawer-navigator.html)

You have to use React.Component instead of Component for all classes. I too faced the same issue and its working now with this minor fix

class Screen2 extends React.Component {
  //Screen2 Component
  render() {
    return (
      <View style={styles.MainContainer}>
        <Text style={{ fontSize: 23 }}> Screen 2 </Text>
      </View>
    );
  }
}

This issue can be for haven't installed Android SDK platform 25 Do this :

  1. Open Android Studio
  2. Open SDK Manager
  3. Click SDK Platforms Tab
  4. Select android 7.1.1 (Nougat) API level is 25
  5. Apply

After installing that press OK and try again to build the project.

# Use of react-navigation (3.x) version ^3.0.0 #

import {
    createDrawerNavigator,
    createStackNavigator,
    createBottomTabNavigator,
    createAppContainer,
} from 'react-navigation';


const AppNavigator = createStackNavigator({
  Home: { screen: HomeScreen }
});

export default createAppContainer(AppNavigator);

Replace this Code :

import { createDrawerNavigator, createStackNavigator } from 'react-navigation';

With this import of your project :

import { DrawerNavigator, StackNavigator } from 'react-navigation';

i hope this help you !
