Question

这是关于如何将Compass与Grunt一起使用的问题。数据填充步骤出了问题。我注意到在控制台上，当我只修改.scss文件时，指南针会多次填充同一个文件（四，五或十到十）。在您看来，它取决于什么？这是我的gruntfile.js。谢谢你的帮助。

module.exports = function (grunt) {

var _homeJs = ['contents/js/jquery.Cinema.js', 'contents/js/jquery.SkinOverlay.js'];
var _homeJsExclude = []

_homeJs.forEach(function (entry) {
    _homeJsExclude.push('!' + entry)
});


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

    concat: {
        dist: {
            src: ['contents/js/*.js', _homeJsExclude],
            dest: 'contents/dist/js/global.js'
        },
        lib: {
            src: 'contents/plugins/**/*.js',
            dest: 'contents/dist/js/libs.js'
        },
        globalhome: {
            files: {
                'contents/dist/js/global.home.js': _homeJs
            }
        }
    },
    uglify: {
        dist: {
            src: ['<%= concat.dist.dest %>'],
            dest: 'contents/dist/js/global.min.js'
        },
        globalhome_min: {

            }

                },

        },
        css: {

            tasks: ['concurrent:target'], 
            options: {
                reload: true
            }

    },
});

grunt.loadNpmTasks('grunt-contrib-uglify');

你在这里遇到了一些问题......首先，你已经在watch任务中compass了你的sass文件，没有必要用明确的{{{}来监控它们。 1}}任务。此外，您的watch任务设置为在sass文件更改后再次运行concurrent。

这是您现在设置的逻辑流程：

启动watch，等待sass OR编译的css文件更改
当sass文件发生变化时，watch执行watch，然后执行concurrent，然后另一个compass 的实例。
watch任务会编译您的css，这会导致compass任务检测到更改并再次运行watch任务。
这种情况会持续下去并破坏一切。

所以，不要使用现有的，只需使用这个（简化的）配置：

concurrent

你把整个事情踢掉了：

grunt.initConfig({
    // ...

    compass: {
        dist: {
            options: {
                sassDir: 'contents/sass/',
                cssDir: 'contents/dist/css',

                // *** remove this option
                // watch: true,

                outputStyle: 'compressed',
                linecomments: false
            }
        }
    },
    // ...

    // *** remove this whole task, in the current config you do not need it
    /*
    concurrent: {
        target: {
            tasks: ['compass', 'watch'],
            options: {
                logConcurrentOutput: true
            }
        }
    },
    */
    watch: {
        // ...

        css: {
            // *** only watch the source files, not the output
            files: ['contents/sass/**/*.scss'],
            // *** run the `compass` task directly
            tasks: ['compass'], 
            options: {
                reload: true
            }
        }
    }
});

或者，如果您想先运行指南针，请注意更改：

~/my-project$ grunt watch
