我也遇到过这个问题。我解决了下面这一步。

在Environment Veritable中检查android sdk路径。

添加 系统变量中的ANDROID_HOME = C:\Users\user_name\AppData\Local\Android\Sdk 而且 C:\Users\user_name\AppData\Local\Android\Sdk\platform-tools路径在“系统变量”中

替换sharedBlacklist如下代码段

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

在node_modules / metro-config / src / / blacklist.js违约

然后执行npx react-native run-android——port 9001

编码. .快乐!

    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

模拟器上的错误信息有点误导人。我用的是Macbook。我需要通过运行$ chmod 755 ./gradlew来更改android/gradlew的权限，然后可以构建应用程序并将其部署到android模拟器。

在我的工作空间尝试解决这个问题后，我找到了一个解决方案。

此错误是因为Metro使用NPM和Node版本的某些组合时出现了问题。

你有两个选择:

Alternative 1: Try to update or downgrade npm and node version. Alternative 2: Go to this file: \node_modules\metro-config\src\defaults\blacklist.js and change this code: var sharedBlacklist = [ /node_modules[/\\]react[/\\]dist[/\\].*/, /website\/node_modules\/.*/, /heapCapture\/bundle\.js/, /.*\/__tests__\/.*/ ]; and change to this: var sharedBlacklist = [ /node_modules[\/\\]react[\/\\]dist[\/\\].*/, /website\/node_modules\/.*/, /heapCapture\/bundle\.js/, /.*\/__tests__\/.*/ ]; Please note that if you run an npm install or a yarn install you need to change the code again.

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

在我的例子中，模拟器的Wifi和移动数据是关闭的。
