React Native module.js throw err

---

在运行 react-native提供的example的时候遇到这个错误。

~/react-native/packager ~
module.js:440
throw err;
^
Error: Cannot find module 'core-js/fn/array/values'

这个错误产生的原因是example找不到node_modules. 可以看下react-native 目录下面是否有node_modules. 解决办法是跑到react active 目录下执行 npm install.

$ cd react-native & npm install
