undefined 不是一个对象(评估 'RootComponent.prototype') [英] undefined is not an object (evaluating 'RootComponent.prototype')

问题描述

---------index.js--------

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

AppRegistry.registerComponent('form1', () => Navigate);

----Navigate.js-----

import React from 'react';
import { StackNavigator, DrawerNavigator } from 'react-navigation';
import TabsList from './TabsList';

export const StackTab1 = StackNavigator({
    TabList: { screen: TabsList},
});

export const Navigate =  DrawerNavigator(
    {
       Tab1: { screen : StackTab1 },
       Tab2: { screen : StackTab1 },
       Tab3: { screen : StackTab1 }
    });

每当我尝试运行我的 android 模拟器时，我都会收到该错误.所有模块都已安装，除了我的模拟器中出现的模块外，我的 IDE 中没有抛出任何错误.

Whenever I try to run my android simulator, I'm getting that error. All modules are installed, no errors being thrown within my IDE except for the one that's appearing in my simulator.

错误如下图:

推荐答案

您没有正确导入 Navigate.

使用

import { Navigate } from './Navigate';

代替

import Navigate from './Navigate';
