问题描述

运行 npm run dev 启动项目报错 await import('source-map-support').then((r) => r.default.install())

原因分析：

目前我的 nodeJS 版本是 14.1.0，初步怀疑是 nodeJS 版本引起的 vite 报错

PS D:\study\electron\electronDemo> nvm ls16.19.016.15.014.19.314.18.3* 14.1.0 (Currently using 64-bit executable)12.19.0
PS D:\study\electron\electronDemo>

解决方案：

采用 nvm 切换管理 nodeJS 版本，关于 nvm 的使用，请自行搜索资料。

PS D:\study\electron\electronDemo> nvm ls16.19.016.15.014.19.314.18.3* 14.1.0 (Currently using 64-bit executable)12.19.0
PS D:\study\electron\electronDemo> nvm use 16.19.0
Now using node v16.19.0 (64-bit)
PS D:\study\electron\electronDemo> nvm ls* 16.19.0 (Currently using 64-bit executable)16.15.014.19.314.18.314.1.012.19.0
PS D:\study\electron\electronDemo>

再次启动项目，成功执行：

PS D:\study\electron\electronDemo> npm run dev> electronDemo@0.0.1 dev
