启动gulpfile.js时出错

Question

我收集测试gulpfile.js，当我在控制台中运行“ gulp js：build”命令时，出现错误。谁知道如何解决？在哪里可以找到这些文件？

    gulp.task('js:build', function () {
    gulp.src(path.src.js) 
        .pipe(rigger()) 
        .pipe(sourcemaps.init()) 
        .pipe(uglify()) 
        .pipe(sourcemaps.write()) 
        .pipe(gulp.dest(path.build.js)) 
        .pipe(reload({stream: true})); 
});

Console Error:
