Gulp 大口喝这么慢，为什么？

我正在启动一个新的项目，使用yeoman这台流行的发电机。 但是gulp在我的macbook pro上用16G内存启动时速度非常慢：

gulp serve

我安装了gulpt来显示每个依赖项加载所需的时间，结果如下

有人有什么办法解决这个问题吗？

很难说没有看到你的肚子。是否可以重构您的gulpfile，使其在需要依赖项之前只需要

即可（例如在任务中）？gulp文件是yeoman gulp angular generator默认生成的文件，无需修改。我想知道同样的事情。运行“gulp serve”时您是否有internet连接？如果没有，将online:true设置为browserSync.init可能会修复此问题。
