按照下面文档的步骤配置React Native的环境：

http://reactnative.cn/docs/0.20/tutorial.html#content

1.react-native init AwesomeProject

2.然后在AwesomeProject目录下运行react-native run-android

然后报错：

Watchman:  watchman--no-pretty get-sockname returned with exit code null dyld: Library not loaded: /usr/local/lib/libpcre.1.dylib
  Referenced from: /usr/local/bin/watchman
  Reason: image not found

还好找到了一篇文章太给力了！

然后我就乖乖的执行了这一步操作

$ brew uninstall pcre && brew install pcre

然而还是有错

Error: The `brew link` step did not complete successfully The formula built, but is not symlinked into /usr/local Could not symlink lib/libpcre.1.dylib

/usr/local/lib is not writable.

解决方法如下：

将brew转换到root模式

sudo chown root:admin /usr/local/bin/brew

sudo brew link pcre

把brew再切换到原来的用户和组

sudo chown zuoyamin:admin /usr/local/bin/brew

结束了上述操作之后，继续参考上篇文档，把AwesomeProject的悬浮框显示出来，然后点击Dev Settings -> Debug server host & port for device

输入：192.168.1.132:8081（注意格式要正确不然会崩）

然后齐活！
