vue3项目升级报错“[vite] : Failed to resolve import "@vue/server-renderer"

前言

最近打算对项目内的vite、vue 和 element-plus 版本升级, 安装完毕之后启动项目，结果不出意外的出意外了

点进去看下怎么回事

根据警告和报错有点懵，看起来routerview有问题？然后顺势也吧vue-router也升级到最新，结果发现并没有用。没办法，逐个排查吧。

寻找原因

先回退版本，重新挨个升级看下报错情况，经过排查发现问题出在vite上，原来的vite版本是 2.5.4，升级到2.9+就又出现问题了

解决问题

既然找到一点眉目那就再查找一下关于vite的依赖项，其中一个官方插件 @vitejs/plugin-vue在GitHub仓库里看到有个关于更新依赖的提交，对照了下项目的版本似乎差了有亿点多，接着把它升级到最新，重启项目，成功！
