          dest: 'assets/javascripts/min/'
        }]

    }
 });


  sass: {
        // this is the "dev" Sass config used with "grunt watch" command
        dev: {
            options: {
                style: 'expanded',
                // tell Sass to look in the Bootstrap stylesheets directory when compiling
                loadPath: 'assets/stylesheets/sass/'
            },
            files: {
                // the first path is the output and the second is the input
                'sass/main.css': 'assets/styleheets/sass/main.scss'
            }
        },
        // this is the "production" Sass config used with the "grunt buildcss" command
        dist: {
            options: {
                style: 'compressed',
                loadPath: 'assets/stylesheets'
            },
            files: {

        }
    },
    // configure the "grunt watch" task
    watch: {
        sass: {
            files: 'sass/*.scss',
            tasks: ['sass:dev']
        }
    }
});
 // loadNpmTasks
 grunt.loadNpmTasks('grunt-contrib-uglify');
 grunt.loadNpmTasks('grunt-contrib-sass');
 grunt.loadNpmTasks('grunt-contrib-watch');

 // Run Default task(s).
grunt.registerTask('default', ['uglify', 'watch', 'buildcss']);
};

您的定义没有正确嵌套，您应该在sass块中移动watch和grunt.initConfig，并将grunt.registerTask, grunt.loadNpmTasks指令移到function(grunt) {}的末尾阻止，就像那样：

module.exports = function (grunt) {
    grunt.initConfig({
         uglify: {},
         sass : {},
         watch : {}
    });

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

    grunt.registerTask('default', ['uglify', 'watch', 'buildcss']);
};
