为什么 Gulp 运行没有错误，但没有编译 SCSS 脚本？

如何解决为什么 Gulp 运行没有错误，但没有编译 SCSS 脚本？

我设置了我的 Gulpfile，到目前为止它看起来不错。我没有错误了。他编译的时候看起来有点太快了。但如果他真的愿意做这份工作，这不会有任何问题。但是当我运行我的 gulp css 任务时，它没有将我的 SCSS 文件编译成 CSS，也没有在之后创建缩小的、连接的构建文件。我检查了路径并在互联网上搜索了解决方案，但这并没有进一步帮助我。 我没有错误。那他为什么不做这份工作呢？我在 gulpfile 中犯了一个错误吗？我用于运行任务异步函数以避免错误。但它似乎只是让错误消失，但它不起作用。有人知道我需要改变什么吗？

这就是我的控制台在运行 gulp css 后所做的：
