Question

在编辑我的SASS文件时使用grunt-watch时，如果我收到SASS错误，我必须在纠正错误后保存两次才能解决。这是事件的顺序：

我添加了一个在我的SASS文件中不存在的mixin并保存
grunt-watch抛出SASS错误
我修正错误并保存
grunt-watch抛出相同的错误
我再次保存
grunt-watch正确编译

这是我的Gruntfile.js：

module.exports = function(grunt) {

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

        imagemin: {
            dynamic: {
                files: [{
                    expand: true,
                    cwd: 'assets/img',
                    src: ['assets/img/**/*.{png,jpg,gif}'],
                    dest: 'assets/img'
                }]
            }
        },
        sass: {
            dist: {
              options: {
                loadPath: require('node-neat').includePaths,
                style: 'compact',
                lineNumbers: true,
                cacheLocation: 'assets/sass/.sass-cache'
              },
              files: [{
                expand: true,
                cwd: 'assets/sass',
                src: ['*.scss'],
                dest: 'assets/css',
                ext: '.css'
              }]
            }
          },
        watch: {
            options: {
                livereload: true
            },
            css: {
                files: ['assets/sass/**/*.scss'],
                tasks: ['newer:sass'],
                options: {
                    spawn: false
                }
            },
            images: {
                files: ['assets/img/**/*.{png,jpg,gif}'],
                tasks: ['imagemin'],
                options: {
                    spawn: false
                }
            },
            js: {
                files: ['assets/js/**/*.js'],
                options: {
                    spawn: false
                }
            },
            html: {
                files: ['*.html'],
                options: {
                    spawn: false
                }
            },
            php: {
                files:['**/*.php'],
                options: {
                    spawn: false
                }
            }
        }

    });

    // List plugins we're using
    grunt.loadNpmTasks('grunt-contrib-watch'); // Watch - http://goo.gl/yxNE0
    grunt.loadNpmTasks('grunt-contrib-imagemin'); // Image Minify - http://goo.gl/mkIRPE
    grunt.loadNpmTasks('grunt-contrib-sass'); // SASS - http://goo.gl/pCHySn
    grunt.loadNpmTasks('grunt-newer'); // Newer - https://goo.gl/3vBTnf

    // Plugins to run when we run the 'grunt' command
    grunt.registerTask('default', [
        'imagemin',
        'sass'
    ]);

};

事实证明Watch中的神秘spawn选项实际上需要为此特定实例设置为true。像大多数人一样，我真的不知道spawn是如何工作的，但它解决了这个问题。

    watch: {
        css: {
            files: ['assets/sass/**/*.scss'],
            tasks: ['newer:sass'],
            options: {
                spawn: true
            }
        }
    }

您不必将选项明确设置为true，默认情况下设置它，因此您根本不能添加它。我只是把它包括在这里作为一个例子。
