推荐答案

我认为这是由于项目名称与您注册的组件不匹配而导致的错误.

I guess it is an error caused by not matching name of project and your registered component.

您已经使用一个名称(即

You have inited project with one name, i.e.

react-native init AwesomeApp

但是在index.ios.js文件中，您注册了其他组件

But in your index.ios.js file you register other component

AppRegistry.registerComponent('Bananas', () => Bananas);

必须必须出现时

AppRegistry.registerComponent('AwesomeApp', () => Bananas);

如果您的组件名称确实匹配，请确保您没有在其他终端中运行任何其他react-native/node进程.

If your component name does match, ensure you don't have any other react-native/node process running in another terminal.
