我在 linux 机器上安装了 react native。我想在我的练习代码中实现 createBottomTabNavigator。我在其中创建了 5 个文件夹和 index.js。导航.js：

import {createAppContainer} from 'react-navigation';
import {createBottomTabNavigator} from 'react-navigation-tabs';

import Profile from './common/pages/profile';
import Home from './common/pages/home';
import Search from './common/pages/search';
import Camera from './common/pages/camera';
import Notification from './common/pages/notification';

const Navigate=createBottomTabNavigator({
    Profile:{screen:Profile},
    Home:{screen:Home},
    Camera:{screen:Camera},
    Search:{screen:Search},
    Notification:{screen:Notification}
});
export default createAppContainer(Navigate);

和主要的 index.js：

import {AppRegistry} from 'react-native';
import Navigate from './navigate';
import {name as appName} from './app.json';

AppRegistry.registerComponent(appName, () => Navigate);

现在当我在 genymotion 中运行时出现错误：

  • null 不是对象''评估_ReanimatedModule.default.configureProps'

我的 package.json：

{
  "name": "myinstagram",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "react-native start",
    "test": "jest",
    "lint": "eslint ."
  },

  },

检查您是否在getPackages下的 MainApplication.java 中添加了新的 ReanimatedPackage()

并添加导入：import com.swmansion.reanimated.ReanimatedPackage；

如果你使用 react-native 0.6，你只需要添加 import com.swmansion.reanimated.ReanimatedPackage;你的 MainApplication.java

但是它应该自动添加这一行，因为 0.6 支持自动链接，但由于某种原因它有时不会添加这一行，所以请务必检查！

只需导入它，一切都会正常工作。

（在 React-Native 0.61.4 上验证）

如果您使用的版本少于 0.6，请使用 @Maksym Bezruchko 解决方案

在 android 文件夹中，android>app>src>main>java>com>app_name>MainApplication.java文件：添加以下导入

import com.swmansion.reanimated.ReanimatedPackage;

希望这会有所帮助，干杯！
