有个开源项目是用hbuilder编译的，现在想通过vue cli实现。本文记录过程中的采坑
创建一个空的uni-app工程
npx degit dcloudio/uni-preset-vue#vite my-vue3-project然后把之前项目里的文件搬过来，如果嫌麻烦，也可以把这个项目package.json里的，把scripts、dependencies、devDependencies合并一下，创建一个src文件夹，把该搬到src里面的搬到src里面。
问题解决
没有sass
直接安装一下就行，我安装的是1.57.1。
Failed to resolve import "@vue/composition-api/dist/vue-composition-api.mjs"
这个是pinia会用到的，按照提示，我尝试了npm i --save @vue/composition-api会报如下错误：
Could not resolve dependency: npm ERR! peer vue@">= 2.5 < 2.7" from @vue/[email protected].
这个本质上是uniapp用的vite版本的问题，是4，改成了3就可以了。附录里的，devDependencies有写"vite": "3.2.4"。
附录
下面是我使用到的package.json里面的一些需要合并的东西
