CSS precompiling does not work in JavaScript API

[KAWATAAAAAA]

At the use Javascript API case ：

Less (maybe SASS etc) in the application doesn't work. It prompts that you need to install it to run.

It doesn't work to install less in the application, but it can be solved in the CLI tool based on the secondary development of vite, but I think it should not be installed in the CLI tool project, but should be explicitly installed in the application

  const command = "serve"
  const mode = "development"
  import { InlineConfig } from "vite"
  import vue from "@vitejs/plugin-vue"
  import { babel } from "@rollup/plugin-babel"
  const { createServer } = require("vite")

  const path = require("path")
  const userConfig = require(`${process.cwd()}/tiny.config`)
  const target = typeof userConfig === 'function' ? userConfig(command,mode) : userConfig

const tinyCliConfig = {
  
    configFile:false,//tiny.config.js
    root:process.cwd(),
    plugins: [
        vue(),
        babel({
          babelHelpers: "bundled",
          exclude: "node_module/**"
        })
      ],
    resolve:{
        alias: {
          "@": path.resolve(process.cwd(), "src"),
        },
      },
}
const finalConfig:InlineConfig = {
    ...userConfig,
    ...tinyCliConfig
}
console.log(finalConfig)
module.exports = async () => {
    // process.cwd  current workplace dir
    // __dirname  current runtime module dir
    const server = await createServer(finalConfig)
    await server.listen()
}

FYI this only happens when you are linking your CLI locally, but it's fixed anyway.
