我完全按照以下说明操作： https://www.npmjs.com/package/react-native-splash-screen 以及观看介绍相同步骤的 YouTube 视频。

我的代码是：

import * as React from 'react';    
import SplashScreen from 'react-native-splash-screen';
import HomePage from './src/Home';
import {navigationRef} from './RootNavigation';
import * as RootNavigation from './RootNavigation.js';

const Stack = createStackNavigator();

export default class App extends React.Component {
  componentDidMount() {
    setTimeout(1000);
    SplashScreen.hide();
  }
  render() {
    return (
      <NavigationContainer ref={navigationRef}>
        <Stack.Navigator>
          <Stack.Screen
            name="Home"
            component={HomePage}
          />
        </Stack.Navigator>
      </NavigationContainer>
    );
  }
}

应用程序运行完全符合要求，但只有 Web 我删除了 componentDidMount 方法。我设置 SplashScreen.hide(); 的行是导致错误的原因。

我收到的错误是：

TypeError: null is not an object (evaluating '_reactNativeSplashScreen.default.hide')

This error is located at:
    in App (at renderApplication.js:45)
    in RCTView (at AppContainer.js:109)
    in RCTView (at AppContainer.js:135)
    in AppContainer (at renderApplication.js:39)

componentDidMount
    App.js:47:4

我尝试手动安装，确保安装了 react-native-splash-screen 并运行 npm install，但似乎没有任何效果。
