在地铁黑名单中更新此部分

var sharedBlacklist = [
  /node_modules[\/\\]react[\/\\]dist[\/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

在我的例子中，模拟器的Wifi和移动数据是关闭的。

你还没有启动捆扎机呢。在项目的根目录下运行npm start或react-native start，然后再执行react-native Run -android。

我经历过这种情况，只是因为我的模拟器错误地关闭了Wifi。我把它重新打开，它开始正常工作。希望对大家有所帮助

如果你已经尝试了上述解决方案中的所有方法，可以尝试以下步骤:

在android/app/src/main/assets中创建文件 执行如下命令:

React-native bundle——platform android——dev false——entry-file index.js——bundle-output android/app/src/main/assets/index.android。Bundle——assets-dest android/app/src/main/res

现在运行命令构建react-native run-android

    this works for me on ubuntu
    
    1. if you are having node version 17 first downgrade its version:-
    You can use n for node's version management.
    
    this is very easy to use.
    $ npm install -g n
    
    then you can show your node version:
    $ node -v
    v16.13.2
    
    2. create an assets folder inside root of the project:-
    project\android\app\src\main\assets
    set folder name should be assets

3. now the final step implement the given code inside the project folder:- 

$cd project 
/project$ react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

4. after following all these step react-native was successfully running on my pc
