RN新手根据官方文档跑Getting Started的例子，出现以下报错：

** BUILD FAILED **


The following build commands failed:

问题所在："react-native": "0.45.1"国内镜像安装导致boost1.63.0和folly-2016.09.26.00文件不完整。

解决办法：重新下载boost1.63.0和folly-2016.09.26.00，替换项目里的。

下载地址：.rncache下载
下载文件中包含了node_modules/react-native/third-party下的所有完整文件，可根据Xcode报错提示进行相应的文件替换。

或者试试，将下载好的.rncache里的三个文件放入Users/username（macOS 系统）目录下的.rncache，如果没有该目录。则使用mkdir .rncache 创建。
