问题与疑问

我一直在CSS代码方面遇到问题，所以现在我总是使用SaSS代码。但是我的问题是：如何将SaSS用于ASP.NET MVC应用程序？

我试过了

我尝试过为此使用Gulp任务。我用过这些命令

npm init
npm install --save gulp
npm install --save gulp-sass

这是我的package.json文件：

{
  "name": "markeonline",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "Hein Pauwelyn",
  "license": "ISC",
  "dependencies": {
    "gulp": "^3.9.1",
    "gulp-sass": "^3.1.0"
  }
}

这里是 gulpfile.js

var gulp = require("gulp"),
    sass = require("gulp-sass");

// other content removed

gulp.task("sass", function () {
    return gulp.src('./**/*.scss')
      .pipe(sass())
      .pipe(gulp.dest(project.webroot + './MarkeOnline.Website/Content/css'));
});

这是我的项目结构：

如果我使用以下命令，此代码将给我以下错误：

gulp sass
