Question

我用下面的教程在线：

https://facebook.github.io/react-native/docs/integration-with-existing-apps.html

它使用以下项目：

https://github.com/JoelMarcey/swift-2048

我试图整合现有的我使用React Native的iPhone和Android应用程序。我用swift在网站上的示例，我无法获得npm start工作。我得到以下错误：

[4:38:11 PM] <START> Building Dependency Graph 
[4:38:11 PM] <START> Crawling File System 
[Hot Module Replacement] Server listening on /hot 

React packager ready.

这是它说npm start的步骤。有什么我可以从上面推断吗？任何帮助赞赏，因为我真的卡住了。我的版本是：

react-native-cli: 1.0.0 
react-native: 0.26.1 
node: 6.2.0 

我也使用nvm如果重要的话。

您是否已安装watchman？ （有关macOS依赖项的列表，请参阅here）。

您可以使用brew install watchman安装它（假设您有homebrew）。
