javascript - 无法运行 Grunt `watch` 任务？

Question

下面是我的 Grunt 文件。我的 watch:news 命令似乎不起作用，我不确定原因。

当我在详细模式下运行时，我可以看到所有 NPM 模块都已加载，没有问题，并且它验证了 watch:news 任务正在按应有的方式运行，但它只是没有'发现发生了任何变化？

我确定这可能是一个拼写错误或一些小的/容易解决的问题，我就是无法发现它？

非常感谢任何帮助!

        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
            grunt release -v

发现问题与观看 <%= sass.news.src %> 有关这不起作用，因为我们正在使用 Grunt 的扩展目录 globbing。

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