Question

当我运行'grunt server'时，一切都会执行，包括编译我的Sass。在保持express和livereload服务器的功能的同时，我应该如何继续观察Sass更改并执行指南针？

当我更改文件时，一切正常，包括livereload，唯一没有的是如果我更改Sass文件则执行指南针重新编译。它甚至可以检测到更改，但不会运行它。

我附加了gruntfile的相关部分，只是为了尽量缩短它。

'use strict';

module.exports = function (grunt) {

如果您使用的是grunt-contrib-compass，我建议您使用原生罗盘观察器。它的工作速度比使用grunt重建要快得多。如果启用它，则必须通过grunt-concurrent，更多信息here运行它。

如何在运行快速服务器时通过grunt watch执行指南针？
