Grunt Watch 不在保存时创建文件

Question

我的 g运行t 文件中的任务运行ning 没有错误，但我要求它创建的文件没有被编译。如果我简单地创建它们运行 'grunt' 但如果我使用 'grunt watch' 并保存文件它不会更新。

特别是我正在处理文件 'script/src/latestNews.js'，因此保存它应该与其他文件合并以创建 'script/dist/main.js'，它确实如此。但它并没有像它应该的那样继续创建 'dist/build.min.js' 。

module.exports = function (grunt) {

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

        uglify: {

            options: {
                mangle: false
            },

            target: {
                files: {
                    'script/dist/main.min.js':'script/dist/main.js'
                }
            },

            build: {
                files: {
                    'script/dist/build.min.js':'script/dist/build.min.js'  
                }
            }

        },

        concat: {
            options: {
                stripBanners: true,
                banner: '/*! <%= pkg.name %> - v<%= pkg.version %> - ' +

Answer 1

您的 watch:js 任务运行的任务数组似乎只是缺少几个关键任务。具体来说，您没有运行执行 concat:build 和 uglify:build 任务。

您当前的任务列表： ['concat:srcJS', 'uglify:target', 'jshint:main', 'copy:js']

Complete/fixed 任务数组： ['concat:srcJS', 'uglify:target', 'jshint:main', 'concat:build', 'uglify:build', 'copy:js']

用我提供的修复程序替换您当前的阵列应该可以解决您的问题。
