Metro bundler：错误：EISDIR：对目录的非法操作，读取

如何解决Metro bundler：错误：EISDIR：对目录的非法操作，读取

当我重新加载我的包时，这个异常没有被捕获：

Error: EISDIR: illegal operation on a directory,read

解决方法

替换`MainApplication.java中的这段代码

        @Override
        protected String getJSMainModuleName() {
          return "src/index"; <---add this
        }

,

显然，将 index.js 移至 src/index.js 存在问题。我将它移回项目根目录，现在工作正常。

,

对于IOS

// packages/myapp/ios/myapp/AppDelegate.m:56
  return [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"src/index" fallbackResource:nil];

,

通过删除和创建新的android模拟器解决...

如果您对本机模块使用 create-react-native-library 并收到此错误。执行以下操作：

1. cd example
2. npx react-native start
3. 在 rootDir 中，yarn example run
