创建compass项目

先创建文件(例:works)--------> 指定到这个文件  cd works  

compass create learn-compass-init //(init项目名字)

项目创建完成------> 创建中出现的提示:

恭喜你的compass文件创建成功

1、按需编译:使用命令  compass compile[path/to/project (项目路径-可选参数)]

2、监听文件的变化并且自动编译:使用命令  compass watch[path/to/project (项目路径-可选参数)]

进入项目目录cd learn-compass-init 实现监听:

compass watch

 

 

 

 

scss转化sass命令:
