使用 electron-updater 更新 electron 应用，打完包安装启动出现这种报错：Cannot find module 'debug'，Cannot find module 'builder-util-runtime'。

项目依赖

问题原因

因为项目使用 pnpm 安装依赖，打完包后有些资源找不到，导致这种很奇怪的报错（Cannot find module 'xxx'）。

问题解决

1. 在项目根目录下，新建 .npmrc 文件。
2. 配置

node-linker=hoisted

设置了 node-linker=hoisted ，pnpm 就会形成扁平化的结构，然后 electron-builder 会自动寻找依赖进行打包，就不会出现这种 Cannot find module 'xxx' 包找不到的情况。
