Grunt-contrib-watch没有看到新的文件
我做了这样的Gruntfile.js：
'use strict'; module.exports = function (grunt) { grunt.loadNpmTasks('grunt-favicons'); grunt.loadNpmTasks('grunt-contrib-imagemin'); grunt.loadNpmTasks('grunt-bake'); grunt.loadNpmTasks('grunt-contrib-htmlmin'); grunt.loadNpmTasks('grunt-contrib-less'); grunt.loadNpmTasks('grunt-autoprefixer'); grunt.loadNpmTasks('grunt-contrib-concat'); grunt.loadNpmTasks('grunt-contrib-uglify'); grunt.loadNpmTasks('grunt-cwebp'); grunt.loadNpmTasks('grunt-responsive-images'); grunt.loadNpmTasks('grunt-retinafy'); grunt.loadNpmTasks('grunt-spritesmith'); grunt.loadNpmTasks('grunt-notify'); grunt.loadNpmTasks('grunt-contrib-watch'); require('load-grunt-tasks')(grunt); grunt.initConfig({ pkg : grunt.file.readJSON('package.json'), watch: { html: { files: ['./assets/**/*.html'], tasks: ['html'], options: { spawn: false, livereload: true, }, }, less: { files: ['./assets/less/**/*.less'], tasks: ['less_files'], options: { spawn: false, livereload: true, }, }, js: { files: ['./assets/js/**/*.js'], tasks: ['js'], options: { spawn: false, livereload: true, }, }, img: { files: ['./assets/images/**/*.png'], tasks: ['img'], options: { spawn: false, livereload: true, }, }, favicon: { files: ['./assets/favicon/favicon.png'], tasks: ['favicon'], options: { spawn: false, livereload: true, }, }, icons: { files: ['./assets/sprites/**/*.png'], tasks: ['icons'], options: { spawn: false, livereload: true, }, }, }, shell: { can_i_use_update: { command: 'npm update caniuse-db' } }, favicons: { options: {}, icons: { src: 'assets/favicon/favicon.png', dest: 'dist/favicons/' } }, imagemin: { images: { options: { optimizationLevel: 4, progressive: true, interlaced: true }, files: [{ expand: true, cwd: './dist/images', src: ['**/*.{png,jpg,jpeg,gif}'], dest: './dist/images/' }] }, favicons: { options: { optimizationLevel: 4, progressive: true, interlaced: true }, files: [{ expand: true, cwd: './dist/favicons', src: ['**/*.{png,jpg,jpeg,gif}'], dest: './dist/favicons/' }] }, sprite: { options: { optimizationLevel: 4, progressive: true, interlaced: true }, files: { './dist/images/sprite.png': './dist/images/sprite.png', } }, }, bake: { build: { options: {}, files: [{ expand: true, cwd: './assets/', src: ['*.html'], dest: './dist/', ext: '.html' }] } }, htmlmin: { dist: { options: { removeComments: true, collapseWhitespace: true, conservativeCollapse: true, preserveLineBreaks: true }, files: [{ expand: true, cwd: './dist/', src: ['**/*.html'], dest: './dist/' }] } }, less: { build: { options: { compress: true, ieCompat: true, sourceMap: true, sourceMapFilename: './dist/css/style.map', sourceMapURL: 'css/style.map' }, files: { "./dist/css/style.css": "./assets/less/style.less" } } }, autoprefixer: { options: { browsers: ['last 5 versions', 'ie 8', 'ie 9', '> 5%'] }, build: { "./dist/css/style.css":"./dist/css/style.css" }, }, concat: { options: {}, dist: { src: ['./assets/js/*.js'], dest: './dist/js/script.js', }, }, uglify: { build: { options: { compress: true }, files: { "./dist/js/script.js":"./dist/js/script.js" } } }, cwebp: { build: { options: { q: 80, alpha_q: 80 }, files: [{ expand: true, cwd: './dist/images/', src: ['**/*.{png,jpg,jpeg,gif}'], dest: './dist/images/webp' }] } }, responsive_images: { build: { options: { engine:"im", sizes: [{ width: 640, },{ width: 1024, },{ width: 1920 }] }, files: [{ expand: true, src: ['**.{jpg,gif,png}'], cwd: './assets/images/', custom_dest: './dist/images/responsive/{%= width %}/' }] } }, retinafy: { build: { options: { sizes: { '75%': { suffix: '@1.5x' }, '100%': { suffix: '@2x' } } }, files: [{ expand: true, cwd: './dist/images/', src: ['**/*.{jpg,jpeg,gif,png}'], dest: './dist/images/' }], } }, sprite:{ all: { src: './assets/sprites/*.png', dest: './dist/images/sprite.png', destCss: './assets/less/sprite.less' } }, notify_hooks: { options: { enabled: true, max_jshint_notifications: 5, // maximum number of notifications from jshint output title: "Project Name", // defaults to the name in package.json, or will use project directory's name success: true, // whether successful grunt executions should be notified automatically duration: 2 // the duration of notification in seconds, for `notify-send only } } }); grunt.task.run('notify_hooks'); grunt.registerTask('html', ['bake', 'htmlmin']); grunt.registerTask('less_files', ['less', 'autoprefixer']); grunt.registerTask('js', ['concat', 'uglify']); grunt.registerTask('img', ['responsive_images', 'retinafy', 'imagemin:images', 'cwebp']); grunt.registerTask('favicon', ['favicons', 'imagemin:favicons']); grunt.registerTask('icons', ['sprite', 'imagemin:sprite']); grunt.registerTask('default', ['html','less_files','js','img','favicon','icons','watch']); }; 一切正常，甚至grunt-contrib手表，但只适用于旧的和修改后的文件。 它没有在监视的文件夹中看到任何新文件。 它不适用于不同版本的grunt-contrib-watch。 有任何想法吗？

我想你应该在开始的时候./ 。 它永远不需要预先。 它可能与这个问题有关， 当前 ./时，它打破了一些事件。
也尝试设置选项是：
options: { event: ['changed', 'added', 'deleted'] }
默认设置被设置为all但是据报道有时它不起作用。
如果全部失败，那么有一个替代解决scheme。 放下grunt-contrib-watch ，试试grunt-simple-watch 。 在这里你可以find为什么grunt-contrib-watch引起麻烦。
附注 ：我意识到，你正在手动加载所有的任务，然后使用load-grunt-task像这样：
grunt.loadNpmTasks('grunt-favicons'); grunt.loadNpmTasks('grunt-contrib-imagemin'); grunt.loadNpmTasks('grunt-bake'); grunt.loadNpmTasks('grunt-contrib-htmlmin'); grunt.loadNpmTasks('grunt-contrib-less'); grunt.loadNpmTasks('grunt-autoprefixer'); grunt.loadNpmTasks('grunt-contrib-concat'); grunt.loadNpmTasks('grunt-contrib-uglify'); grunt.loadNpmTasks('grunt-cwebp'); grunt.loadNpmTasks('grunt-responsive-images'); grunt.loadNpmTasks('grunt-retinafy'); grunt.loadNpmTasks('grunt-spritesmith'); grunt.loadNpmTasks('grunt-notify'); grunt.loadNpmTasks('grunt-contrib-watch'); require('load-grunt-tasks')(grunt);
供你参考; 你不需要加载所有的任务，因为load-grunt-tasks自动为你做。 load-grunt-tasks扫描packages.json文件以获取您拥有的任务并自动加载它们。 你可以安全的删除所有的grunt.loadNpmTasks(xxx) ，这个任务将被加载（只要在packages.json提到）
