我在项目的root中运行npm install，然后当我尝试运行gulp de时，出现以下错误：

$ gulp dev
module.js:442
    throw err;
    ^

the gulp file

我尝试了不同的东西，比如去旧节点，最新的节点，重新安装的节点，npm和gulp数十亿次，但它没有帮助。

它可以是什么以及如何解决它？

当您需要gulpfile中的browser-sync模块时，似乎会发生错误。该模块找不到其中一个组件./lib/public/public-utils，并且无法启动。

我首先检查你的node_modules目录，看看browser-sync发生了什么。它通常是模块的安装损坏。

确保在package.json中列出了最新版本（2.13.0）的浏览器同步，并获得全新安装删除node_modules目录，{{1}并再次运行npm cache clean。

gulp dev因为错误而无法运行
