Grunt构建不会创建css文件

Question

我是Yeoman和Grunt的新手.

在进行Grunt构建时,构建似乎成功结束但是没有创建dist/styles/*.css文件.

从日志中看起来样式被编译为.tmp/styles /(参见下面的"compass:dist"(指南针)任务)但不会被复制或缩小为dist/styles.这就是为什么"usemin:css"(usemin)不存档文件. - 但这只是猜测.

我使用的是由yeoman生成的基本Gruntfile.info(我在下面添加了它),我做的唯一更改是注释掉cssmin任务,因为我假设做同样的事情.

这是构建输出:

          src:

您的HTML中可能存在问题,可能您忘记为grunt任务添加注释.

<!-- build:css(.) styles/vendor.css -->
<!-- bower:css -->
<link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.css" />
<!-- endbower -->
<!-- endbuild -->

开箱即用的Yeoman需要根据我的经验进行一些调整.这是Grunt引擎真的想要缩小一些东西 - 这是它的主要增值之一.我也很陌生,但我想在grunt文件中空的cssmin区域会让你感到烦恼.尝试将这样的东西放到你的gruntfile.js的cssmin区域 -

    cssmin: {
        dist: {
            files: {
                '<%= yeoman.dist %>/styles/main.css': [
                    '.tmp/styles/{,*/}*.css',
                    '<%= yeoman.app %>/styles/{,*/}*.css'
                ]
            }
        }
    },

你应该给你的css缩小一些牙齿.然后,您将在gruntfile.js底部的构建任务中取消注释cssmin,以便在CLI上执行"grunt build"时运行它.
