如何修复gulp-sass安装错误

Question

我是Gulp的新手，我想为我的项目安装gulp-sass。但它会抛出错误。我试着安装另一个像gulp uglify这样的gulp包，我对它们没有任何问题。它抛出的错误仅仅是吞咽--sass。我重新安装并更新了节点，但没有任何变化。我该如何解决这个问题呢？这是错误：

您的node.js版本是什么？当我使用Node15.x版本时，我看到了这个错误。但是在我重新安装了14.x版本之后，我可以成功地安装gulp-sass模块。使用最新版本的Node.js并不好。为了获得良好的体验，最好使用LTS版本(必须在生产环境中使用)。https://nodejs.org/en/about/releases/
