使用 Grunt watch 和 SASS 时出错

Question

我正在尝试在 Windows 上将 grunt watch t 与 SASS 一起使用，但每次都出现错误

我在这里找到了similar question，但这对我不起作用

我的 package.json：

{
  "name": "Test",
  "version": "1.0.0",
  "description": "Test thingy",
  "author": "Me",
  "devDependencies": {
    "grunt": "~0.4.1",
    "grunt-contrib-sass": "~0.3.0",
    "grunt-contrib-watch": "~0.4.4"
  }
}

我的 Gruntfile.js

module.exports = function(grunt) {
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        sass: {
            dist: {
                options: {
                    style: 'compressed'
                },
                files: {
                    'css/style.css' : 'sass/style.scss'
                }
            }
        },
        watch: {
            css: {
                files: '**/*.scss',
                tasks: ['sass'],
                options: {
                    spawn: false
                }
            }
        },
    });

    grunt.loadNpmTasks('grunt-contrib-sass');
    grunt.loadNpmTasks('grunt-contrib-watch');

    grunt.registerTask('default',['watch']);
}

软件版本：

grunt-cli v0.1.13

咕噜 v0.4.5

Sass 3.4.13（选择性史蒂夫）

ruby 2.2.2p95（2015-04-13 修订版 50295）[x64-mingw32]

指南针 1.0.3（北极星）

npm 2.7.4

节点 v0.12.2

我已经尝试更新所有软件包，甚至重新安装了所有组件，但这并没有帮助。谁能帮帮我？

尝试禁用源映射，看看它是否有效。

module.exports = function(grunt) {
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        sass: {
            dist: {
                options: {
                    style: 'compressed',
                    sourcemap: 'none'
                },
                files: {
                    'css/style.css' : 'sass/style.scss'
                }
            }
        },
        watch: {
            css: {
                files: '**/*.scss',
                tasks: ['sass'],
                options: {
                    spawn: false
                }
            }
        },
    });

    grunt.loadNpmTasks('grunt-contrib-sass');
    grunt.loadNpmTasks('grunt-contrib-watch');

    grunt.registerTask('default',['watch']);
}

您的 grunt-contrib-sass 版本已过时尝试将 package.json 更改为：

{
  "name": "Test",
  "version": "1.0.0",
  "description": "Test thingy",
  "author": "Me",
  "devDependencies": {
    "grunt": "~0.4.1",
    "grunt-contrib-sass": "~0.9.0",
    "grunt-contrib-watch": "~0.4.4"
  }
}
