Gruntjs “运行”；“指南针手表”；基金会5退回警告声明

运行一个咕噜咕噜的指南针手表会给我警告

以下是我的终端中的错误日志：

Running "watch" task

>> File "source/sass/layout/_navigation.scss" changed.
Running "compass:dist" (compass) task
DEPRECATION WARNING on line 275 of /Users/username/Sites/sitename/www/projectname/bower_components/foundation/scss/foundation/components/_global.scss:
    Assigning to global variable "$default-float" by default is deprecated.
    In future versions of Sass, this will create a new local variable.
    If you want to assign to the global variable, use "$default-float: left !global" instead.
    Note that this will be incompatible with Sass 3.2.

    DEPRECATION WARNING on line 276 of /Users/username/Sites/sitename/www/projectname/bower_components/foundation/scss/foundation/components/_global.scss:
    Assigning to global variable "$opposite-direction" by default is deprecated.
    In future versions of Sass, this will create a new local variable.
    If you want to assign to the global variable, use "$opposite-direction: right !global" instead.
    Note that this will be incompatible with Sass 3.2.

    DEPRECATION WARNING: The return value of index() will change from "false" to
    "null" in future versions of Sass. For compatibility, avoid using "== false" on
    the return value. For example, instead of "@if index(...) == false", just write
    "@if not index(...)".

这是否意味着我必须更新某个NPM包，或者这是在基础框架中？

编辑：运行指南针v1.0.1顺便说一下：

→ compass -v

发现了问题。看来我的无礼已经过时了。是在3.3（Maptastic Maple）上，应该是在3.4（选择Steve）

跑

$sass-v

找出你的版本是什么。如果超过3.4，请运行

$sudo gem安装sass

安装新版本
