无法初始化AwesomeProject React Native

Question

我按照React Native - Getting Started中的所有步骤进行操作。我输入了

> react-native init AwesomeProject

并收到以下错误

This will walk you through creating a new React Native project in 
/Users/invisal/Documents/React/AwesomeProject

Installing react-native package from npm...

npm ERR! Error: Invalid name: "AwesomeProject"
....

我正在运行OS X El Capitan 10.1。有谁知道如何解决这个问题？
