Javascript 另一个文件夹中的节点\u模块

我在C:/Users/user/AppData/Roaming/npm/node_modules路径中拥有所有节点模块。然后我尝试为我的脚本网页包含带有巴别塔和巴别塔预设的node_模块

My webpack.config.js

但巴贝尔并没有看到2015年。我也这么认为

webpack

命令重新发布以下内容：

ERROR in ../main.js Module build failed: Error: Couldn't find preset "es2015"

    at Object.module.exports (C:\Users\user\AppData\Roaming\npm\node_modules\babel-loader\index.js:83:14) @ multi main

请帮忙。错误在哪里？

找到了解决方法

npm链接

它添加了到模块的链接。

为什么不将它们添加到本地的项目中？npm install XXXX--save dev？我试图找到一个节点模块文件夹的多个项目的解决方案。这不是正确的方法，每个节点项目都应该有自己的节点模块文件夹，所有模块都声明在package.json文件中。npm和模块的整个要点是，每个项目都可以有自己的依赖项。
