【问题描述】：

运行 grunt 指南针手表会给我弃用警告。

以下是我终端中的错误日志：

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(...)".

    Done, without errors.

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：顺便运行 compass v1.0.1：

→ compass -v
Compass 1.0.1 (Polaris)

【解决方案1】：

发现问题。看来我的sass已经过时了。使用 3.3 (Maptastic Maple)，应该使用 3.4 (Selective Steve)。

运行

$ sass -v

找出你的版本是什么。如果它早于 3.4 运行

$ sudo gem install sass

安装新版本。
