当我重新加载我的包时，这个异常未被捕获：

在 MainApplication.java 中替换此代码

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

  • How to do this but for IOS?

回答

IOS版

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

回答

显然，转移index.js到src/index.js. 我将它移回项目根目录，现在工作正常。

  • In my project, index.js is in root but still facing the issue. Any idea?
以上是Metrobundler：错误：EISDIR：对目录的非法操作，读取的全部内容。
