Question

第一次运行Grunt和Sass，我在修改scss文件时在终端中收到此错误：

danales-MacBook-Pro:sass-test danale$ grunt
Running "watch" task
Waiting...
>> File "SCSS/_main.scss" changed.
Running "sass:dev" (sass) task

根据我的理解，错误是说我的gruntfile中的路径需要是一个字符串：

module.exports = function(grunt) {

  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),

    /**
    * SASS
    */
    sass: {
      dev: {
      options: {
        style: 'expanded',
          sourcemap: 'none',
        },
        files: {
          'style.css': 'scss/style.css'
        }
      }
    },

    /**
    * watch
    */
    watch: {
        css: {
          files: '**/*.scss',
          tasks: ['sass']
        }
    },
  });
  grunt.loadNpmTasks('grunt-contrib-sass');
  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.registerTask('default',['watch']);
}

但我不清楚哪条路需要成为一个字符串......

它说的是你指向的sass文件不在那里。从watch输出我可以看到该目录实际上被称为SCSS/（与scss/相对）。此外，您还没有指出要预处理的 scss 文件。尝试更改sass任务配置以指示正确的目录和主scss文件：

files: {
    'style.css': 'SCSS/_main.scss'  // update this match your PRIMARY scss file
}

哪条路径需要是一个字符串？
