安装环境：

Mac os X 10.14

必须安装的软件 : Home-brew & Node

推荐安装的工具：Watchman & Flow

Home-brew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

打开终端命令，输入以上的代码，中间会需要按一次return，输入一次开机密码。

安装过程中出现了以下错误：

xcode-select: error: invalid developer directory '/Library/Developer/CommandLineTools'
Failed during: /usr/bin/sudo /usr/bin/xcode-select --switch /Library/Developer/CommandLineTools

解决方案：
用WebStorm打开如下脚本，此为修改后的脚本内容，可直接运行，可以解决上面的问题。

解决思路

用浏览器打开 https://raw.githubusercontent.com/Homebrew/install/master/install ，可以看到文件内容。
修改其安装 Homebrew 的脚本 code 指令后,越过"/Library/Developer/CommandLineTools/" 验证这一环节。

使用 brew 可以查看是否有日志，检查安装是否成功。

Node

使用 Homebrew 来安装Node.js

译注：在 Max OS X 10.11（El Capitan)版本中，homebrew 在安装软件时可能会碰到/usr/local目录不可写的权限问题。可以使用下面的命令修复：

sudo chown -R `whoami` /usr/local

安装完 node 后建议设置 npm 镜像以加速后面的过程（或使用科学上网工具）。注意：不要使用 cnpm！cnpm 安装的模块路径比较奇怪，packager 不能正常识别！

npm config set registry https://registry.npm.taobao.org --global
npm config set disturl https://npm.taobao.org/dist --global

Yarn、React Native的命令行工具（react-native-cli）

Yarn是Facebook提供的替代npm的工具，可以加速node模块的下载。

npm install -g yarn react-native-cli

安装完 yarn 后同理也要设置镜像源：

yarn config set registry https://registry.npm.taobao.org --global
yarn config set disturl https://npm.taobao.org/dist --global

如果你看到EACCES: permission denied这样的权限报错，那么请参照上文的 homebrew 译注，修复/usr/local目录的所有权：

sudo chown -R `whoami` /usr/local

安装完 yarn 之后就可以用 yarn 代替 npm 了，例如用yarn代替npm install命令，用yarn add 某第三方库名代替npm install --save 某第三方库名。
