Answer 1

显然，将 index.js 移动到 src/index.js 时存在问题。我把它移回了项目根目录，现在工作正常。

Answer 2

将此代码替换为`MainApplication.java

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

Answer 3

对于IOS

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

Answer 4

如果您将 create-react-native-library 用于本机模块并收到此错误。执行以下操作：

cd example
npx react-native start
在根目录中，yarn example run

Answer 5

通过删除和创建新的 android 模拟器解决...

Answer 6

我遇到了同样的错误，但在 yarn global remove wml

之后一切正常

yarn global remove wml

救了我的命

如果您从未安装过wml，只需考虑一些其他相关的全局库

----更新----- 即使我卸载了 wml 人员，我再次遇到错误，但我发现我的问题的根本原因是 watchman，在运行 brew uninstall watchman 之后，一切顺利
