我即将为我的公司创建一个模式库。我正在使用以下软件：

  • css-loader@0.23.1
  • 提取-文本-webpack-plugin@1.0.1
  • 节点-sass@3.8.0
  • sass-loader@4.0.0
  • 样式加载器@0.13.1
  • webpack@1.13.2
  • 解析 url-loader@1.6.0
  • 节点@6.3.1
  • npm@3.10.3

在我的电脑上（Windows 10）。

我的目标是使用该@import "colors"语句并获取相应的文件../patterns/globals/_colors.css。我尝试了includePaths带有属性的 sass-loader 和 resolve-url-loader 的配置root。但到目前为止都没有工作......

在我第一次使用 sass-loader 和 includePaths 运行时，我得到了以下错误报告：

二、尝试编译一个简单的sass，内容如下：

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

body {
  font-size: 12px;
}

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

使用提到的 webpack 配置，我没有收到错误消息，但收到了无效的 CSS 代码，如下所示：

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

body {
  font-size: 12px;
}

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

我不明白我失败的根源在哪里。

最好的问候， JBrieske

编辑：在@IRus 的帮助下，我设法解决了我的问题。

模块构建失败：ModuleNotFoundError：找不到模块：错误：无法解析 ~/projects/webpack-sass-fail/app 中的“文件”或“目录”./colors

重命名color为color.scssin typography.scss。或者resolve在 webpack 配置中正确设置。

您尝试使用标准 CSS 解析器解析 SCSS；使用 postcss-scss 解析器重试

ExtractTextPlugin以这种方式更改加载程序：

{test: /\.scss$/, loader: ExtractTextPlugin.extract('style', 'css!resolve-url!sass')}
// or
{ test: /\.scss$/, loader: ExtractTextPlugin.extract('style', ['css', 'resolve-url', 'sass']) }

因为这是等价的：

{test: /\.scss$/, loader: ExtractTextPlugin.extract('style', 'css')}
{test: /\.scss$/, loader: ExtractTextPlugin.extract('style', 'css', 'resolve-url', 'sass')}

比你得到新的错误：

未定义的变量：“$grey”。

这只是 styles.scss 中的拼写错误：

// border: 1px solid $grey;
border: 1px solid $gray;
