我正在使用以下在线教程:

它使用下面的项目:

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

我正在尝试将我现有的iPhone和android应用程序与React Native集成。我在网站上使用了swift的样本，我无法得到npm start的工作。我得到下面的错误:

这一步写的是npm start。从上面我能推断出什么吗?感谢任何帮助，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，如果计数

您是否安装了watchman ?(查看macOS依赖项列表)。

你可以安装brew install watchman(假设你有自制)。
