Javascript jit grunt:；“干净”；找不到任务？

当我运行grunt build时，我遇到了这个错误，你知道如何解决这个问题吗

Running "concurrent:dist" (concurrent) task
    Warning:

    If you have installed the plugin already, please setting the static mapping.

Grunfile.js

  require('jit-grunt')(grunt, {
    express: 'grunt-express-server',
    useminPrepare: 'grunt-usemin',
    ngtemplates: 'grunt-angular-templates',

您需要作为依赖项安装

compass

插件。您可以通过从工作目录执行以下命令来实现这一点

npm install grunt-contrib-compass --save-dev

希望这有帮助
