performance - 与Compass和Watch一起 Grunt 咕slow的编译速度很慢

Question

Grunt需要很长时间来编译css文件，我不确定这是否正常，但是常规的指南针 watch 大约需要5秒钟。

所以问题是，是否有任何方法可以使用Grunt加快编译时间，还是只坚持使用指南针 watch 更好？

Gruntfile.js:

compass: {
        dist: {
            options: {
            config: 'config.rb'
            }
        }
    },

    watch: {
        sass: {
            files: ['scss/*.scss'],
            tasks: ['compass:dist'],
            options: {
                spawn: false,
            }
        },
        scripts: {
            files: ['js/*.js'],
            tasks: ['concat', 'uglify'],
            options: {
                spawn: false,
            }
        }
    }

});

连同Simon关于grunt-contrib-compass的watch选项提到的内容，您可以使用grunt-concurrent来同时运行两个进程，即grunt watch和compass watch:

concurrent: {
    watch: {
        tasks: ['watch', 'compass:watch'],
        options: {
            logConcurrentOutput: true
        }
    }
},
compass: {
    watch: {
        options: {
            watch: true
        }
    }
}

如果要在构建，部署或需要 compile而不是 watch的其他任何操作时从Grunt运行指南针，则需要执行第二个指南针任务并使用该指南针:

compass: {
    // Compass grunt module requires a named target property with options.
    compile: {
        options: {}
    }
}
