如何从当前webpack配置的sass-loader获取有效的css？

我即将为我的公司创建一个模式库 . 我使用以下软件：

• css-loader@0.23.1

• extract-text-webpack-plugin@1.0.1

• node-sass@3.8.0

• sass-loader@4.0.0

• style-loader@0.13.1

• webpack@1.13.2

• resolve-url-loader@1.6.0

• node@6.3.1

• npm@3.10.3

在我的电脑上（Windows 10） .

我的目标是使用 @import "colors" 语句并获取相应的文件 ../patterns/globals/_colors.css . 我创建了一个存储库，以简化代码向您展示我的情况：https://github.com/jbrieske/webpack-sass-fail . 我尝试了sass-loader的 includePaths 配置和带有 root 属性的resolve-url-loader . 但到目前为止两者都没有...

在我的第一次运行（提交：14622da5e6eb77ec51644601b94942c3b51eb76a）与sass-loader和includePaths我得到以下错误报告：

我尝试使用以下内容编译simle sass：

$grey: lightgrey;
$family: "Tahoma";

body {
  font-size: 12px;
}

p {
  border: 1px solid $grey;
  font-family: $family;
}

使用上面提到的webpack配置我没有收到任何错误消息，但是像这样的CSS代码无效：

$family: "Tahoma";
$grey: lightgrey;

body {
  font-size: 12px;
}

p {
  border: 1px solid $grey;
  font-family: $family;
}

我不明白我失败的原因在哪里 .

最好的问候，JBrieske
