【问题描述】：

我正在开发一个已经由某人开发的项目。该项目运行良好，但问题是我需要对 vue 代码进行一些更改并观察这些更改，我需要运行“npm run dev”/“watch”命令，但在尝试时出现以下错误执行它。

PS。我是这个平台的新手，任何提示或建议都会让我的工作变得轻松。谢谢。

【问题讨论】：

你发npm install了吗？
清楚的说是什么问题，“本地的package.json存在，但是缺少node_modules，你的意思是要安装吗？”
@EstusFlask node_module 已经存在..
@Aurel 是的，同样的错误
不知道 node_modules 是如何创建的。尝试删除并重新安装。确保文件 C:\Users\Dell\Desktop\New folder\project\node_modules/webpack/bin/webpack.js 存在，因为它是预期的，你可以在提供的信息中看到这个

【解决方案1】：

我已经删除了节点模块文件夹，在运行“npm install”命令后，我成功地解决了这个问题。以前我正在运行该命令，但我认为我在两者之间退出了操作，这就是它抛出错误的原因。
