为什么 Metro Bundler 声称 app.json 不存在？

问题描述

请注意，这与此处发布的有关缺少模块的其他问题不同。无论我在我的应用程序文件夹中运行 npx react-native run-android 还是 npx react-native start，它似乎都声称我的 app.json 文件丢失了，但它在基本目录中。

    error: Error: Unable to resolve module `./app.json` from `index.js`:
    None of these files exist:
      * app.json
      * app.json\index(.native|.android.js|.native.js|.js|.android.json|.native.json|.json|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx)

index.js

/**
 * @format
 */

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

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