Question

为一些即将开展的项目组建基地Gruntfile.js。从一台新电脑开始，所以一切都是新的。使用Homebrew安装Node和NPM，然后在全局和本地目录中安装Grunt。

这是我的package.json：

{
  "name": "timespent-prototype",
  "version": "0.1.0",
  "devDependencies": {
    "assemble": "0.4.37",
    "bower": "^1.4.1",
    "grunt": "^0.4.5",
    "grunt-contrib-concat": "^0.5.1",
    "grunt-contrib-sass": "^0.9.2",
    "grunt-contrib-watch": "^0.6.1",
    "grunt-newer": "^1.1.0",
    "grunt-wiredep": "^2.0.0"
  }
}

这是我的Gruntfile.js：

module.exports = function(grunt) {

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

    concat: {
      vendor: {
       src: ['vendor/**/*.min.js'],
       dest: 'build/javascripts/library.js',
      }
    },

    // Takes your scss files and compiles them to css
    sass: {
      dist: {
        options: {
          style: 'expanded'
        },
        files: {
          'build/stylesheets/application.css': 'app/stylesheets/application/index.scss'
        }
      }
    },

    // Assembles your templates into HTML files
    assemble: {
      options: {
        layoutdir: 'app/views/layouts/',
        partials: ['app/views/partials/*.hbs'],
        flatten: true,
        expand: true
      },
      pages: {
        src: ['app/views/**/*.hbs','!app/views/layouts/*.hbs','!app/views/partials/*.hbs'],
        dest: 'build/'
      }
    },

    wiredep: {
      task: {
        src: ['app/views/layouts/*.hbs']
      }
    },

    // Watches for file changes, runs the default task
    watch: {
      files: ['app/**/*'],
      tasks: ['default'],
      options: {
        // Start another live reload server on port 1337
        livereload: 1337,
      }
    }

  });

  // Load the plugins
  grunt.loadNpmTasks('assemble');
  grunt.loadNpmTasks('grunt-contrib-sass');
  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-newer');
  grunt.loadNpmTasks('grunt-contrib-concat');
  grunt.loadNpmTasks('grunt-wiredep');

  // Register the tasks
  grunt.registerTask('default', ['sass','assemble']);
  grunt.registerTask('watch', ['watch']);
  grunt.registerTask('concat', ['concat']);
  grunt.registerTask('wiredep', ['wiredep']);
};

我看到的问题是，对于多个任务，特别是wiredep和concat，任务陷入循环并且永远不会结束。使用如下详细输出运行grunt concat：

Registering "grunt-contrib-concat" local Npm module tasks.
Reading /Users/jacksonlynch/projects/timespent-prototype/node_modules/grunt-contrib-concat/package.json...OK
Parsing /Users/jacksonlynch/projects/timespent-prototype/node_modules/grunt-contrib-concat/package.json...OK
Loading "concat.js" tasks...OK
+ concat

Running tasks: concat

Running "concat" task

Running "concat" task

Running "concat" task

Running "concat" task

Running "concat" task

Running "concat" task

Running "concat" task将继续打印，直到我停止。正如我在多个插件和任务中看到的那样，这可能是我安装NPM或Grunt时遇到的问题，但是我很难调试这个。如果有人之前遇到过这种情况，请告诉我有什么帮助！

谢谢！

在Gruntfile.js的最后两行中，您重新声明了concat和wiredep任务，当grunt尝试运行您的代码时，它陷入无限循环，因为concat指的是一个未定义的concat任务，所以你应该删除这些行：

grunt.registerTask('concat', ['concat']);
grunt.registerTask('wiredep', ['wiredep']);

通常，当您使用foobar定义名为grunt.initConfig的任务时，它已定义，无需使用registerTask进行注册，grunt foobar可以访问该任务1}}命令。

Grunt任务陷入无休止的循环中
