我在运行Sass，Compass和Susy。我升级到了最新版本：

代码语言：javascript
复制
bigdecimal (1.2.4)
chunky_png (1.3.3)
compass (1.0.3)
compass-core (1.0.3)
compass-import-once (1.0.5)
ffi (1.9.6 x86-mingw32)
io-console (0.4.2)
json (1.8.1)
minitest (4.7.5)
multi_json (1.10.1)
psych (2.0.5)
rake (10.1.0)
rb-fsevent (0.9.4)
rb-inotify (0.9.5)
rdoc (4.1.0)
sass (3.4.10)
susy (2.2.1)
test-unit (2.1.5.0)

完整的弃用警告为：

代码语言：javascript
复制
DEPRECATION WARNING: Passing null, a non-string value, to unquote()
will be an error in future versions of Sass.

我运行了"compass compile --trace“，但它没有添加任何额外的信息。有人知道如何找到问题所在吗？据我所知可能是罗盘或者苏西。请给我建议。

看起来问题出在指南针上。下面是我的调查，我得出了这个结论。我通过在Sass安装中进行搜索找到了显示此警告的位置(在我的示例中为"C:\Ruby21\lib\ruby\gems\2.1.0\gems\sass-3.4.10\lib\sass").它是"..\scripts\functions.rb"：

代码语言：javascript
复制
    def unquote(string)
      unless string.is_a?(Sass::Script::Value::String)
        Sass::Util.sass_warn(<<MESSAGE)
DEPRECATION WARNING: Passing #{string.to_sass}, a non-string value, to unquote()
will be an error in future versions of Sass.
MESSAGE
        return string
      end

      return string if string.type == :identifier
      identifier(string.value)
    end
    declare :unquote, [:string]

我在“除非”中放了一个“put caller”，看看谁在不带参数的情况下调用这个函数，输出如下：

DEPRECATION WARNING: Passing null, a non-string value, to unquote()
will be an error in future versions of Sass.

正如你所看到的，在堆栈跟踪的底部，指南针正在做事情，它调用Sass。我要把这个问题提交给指南针。

仅供参考:我把这个bug发布到了指南针bug跟踪https://github.com/Compass/compass/issues/1924上。

正如在this thread中提到的，这确实是一个指南针的问题，与它的盒子大小混合有关。您将在该页面上找到可能的解决方案。我将它们复制到这里：

解决方案1(我已经测试过了，警告消失了)：

添加您自己的自定义混合，它将覆盖Compass混合：

代码语言：javascript
复制
@mixin box-sizing($value) {
    -moz-box-sizing: $value;
         box-sizing: $value;
}

解决方案2：

代码语言：javascript
复制
@mixin box-sizing($box-model: $default-box-sizing) {
  @if type-of($box-model) == string {
    $box-model: unquote($box-model);
  }
  @include prefixed-properties(css3-boxsizing, $box-sizing-support-threshold, (box-sizing: $box-model));
}

您可以创建一个安全版本的unquote，因此它不会被调用，除非它真的是一个字符串：

代码语言：javascript
复制
@function safe-unquote($param) {
  @return if(type-of($param) == string, unquote($param), $param);
}
