react-native项目中用到的插件库作用注释

至于shelljs插件，官方说明：

ShellJS is a portable (Windows/Linux/OS X) implementation of Unix shell commands on top of the Node.js API. You can use it to eliminate your shell script's dependency on Unix while still keeping its familiar and powerful commands. You can also install it globally so you can run it from outside Node projects - say goodbye to those gnarly Bash scripts!

 

ShellJS是在Node.js API之上的Unix shell命令的可移植（Windows / Linux / OS X）实现。您可以使用它来消除shell脚本对Unix的依赖，同时仍然保留其熟悉而强大的命令。您还可以全局安装它，以便可以从Node项目外部运行它-告别那些讨厌的Bash脚本！
