javascript – 无法让Grunt`watch`任务运行?

下面是我的Grunt文件.我的观察:新闻命令似乎不起作用,我不知道为什么.

当我以详细模式运行时,我可以看到所有NPM模块都加载没有问题,并且它验证了watch:news任务是否正在运行,但是它只是没有发现任何更改已经发生?

我敢肯定这可能是一个错字或一些小/容易修复的问题,我只是无法发现它?

任何帮助非常感谢!

        Grunt installation:
        -------------------
            npm install -g grunt-cli
            npm install -g grunt-init
            npm init (creates a `package.json` file)

        Project Dependencies:
        ---------------------
            npm install grunt --save-dev
            npm install grunt-contrib-watch --save-dev
            npm install grunt-contrib-jshint --save-dev
            npm install grunt-contrib-uglify --save-dev
            npm install grunt-contrib-requirejs --save-dev
            npm install grunt-contrib-sass --save-dev
            npm install grunt-contrib-imagemin --save-dev

        Example Usage:
        --------------
            grunt -v

    // Default Task
    grunt.registerTask('default', ['jshint', 'sass:dev']);

    // News Task
    grunt.registerTask('news', ['sass:news']);

    // Release Task
    grunt.registerTask('release', ['jshint', 'requirejs', 'sass:dist', 'imagemin']);

};

最佳答案 弄清楚问题与观看<%= sass.news.src%>这不起作用,因为我们正在使用Grunt的扩展目录通配.

解决方案是直接引用我想要观看的文件夹:<%= dir.static_sass%> ** / * .scss’
