配置 gulp-notify 后一直报错

配置文件大概为：

// 引入 gulp
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');
var notify = require('gulp-notify');

// JS 任务
gulp.task('scripts', function() {
    gulp.src(['src/js/*.js'])
        .pipe(concat('main.min.js'))
        .pipe(uglify())
        .pipe(gulp.dest('dist/js'));
        .pipe(notify({ message: 'JS task complete' }));
});

// 默认任务
gulp.task('default', ['scripts']);

// 监听
gulp.watch('src/js/*.js', ['scripts']);

运行起来报错信息：

project/freegapper/gulpfile.js:25
        .pipe(notify({ message: 'JS task complete' }));
        ^

SyntaxError: Unexpected token .

这是什么原因呢？

多写了末尾的;了

.pipe(gulp.dest('dist/js'));
