        }
      }
    }
  });

  // Default task(s). 

  //grunt.registerTask('default', 'compass:dev');

  grunt.registerTask('watch', ['watch']);
  grunt.loadTasks('watch');

  grunt.loadNpmTasks('grunt-contrib-watch');
  grunt.loadNpmTasks('grunt-contrib-compass');
  grunt.registerTask('default', ['compass']);
};

Answer 1

我重新格式化了您的代码，现在您应该看到您已经将watch config放在了compass config对象中，这是不正确的。

另外，您为什么要包含以下代码：？

grunt.registerTask('watch', ['watch']);
grunt.loadTasks('watch');

这可能也会导致一些问题，我建议删除它。

Answer 2

我认为这一节：

grunt.registerTask('watch', ['watch']);
grunt.loadTasks('watch');

grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.registerTask('default', ['compass']);

应该如下所示：

grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-compass');

grunt.registerTask('watch', ['watch']);
grunt.registerTask('default', ['compass']);
