CompileTemplate generates a difference in the render function

[xjArea]

I tried compiling .vue files myself using compiler-sfc, I did succeed, but only for regular <script> tags, when I use <script setup>, the compiled render The function keeps reporting an error. I think it may be a problem with my parameter settings. The following two pieces of code are the results compiled by myself and compiled using vue3-sfc-loader. It can be found that the parameters of the render function are different. Why is this so? , how should I set the parameters to be the same as the content compiled by vue3-sfc-loader.

↓ This is the Counter.vue :

<template>
	<button type="button" @click="count++">{{ count }}</button>
</template>
<script setup>
import {ref, } from 'vue';
let count = ref(0);
</script>

↓ This is vue3-sfc-loader compiled result, it has the $setup option, and it use $setup.count, it can run :

export function render(_ctx, _cache, $props, $setup, $data, $options) {
  return (_openBlock(), _createElementBlock("button", {
    type: "button",
    onClick: _cache[0] || (_cache[0] = $event => ($setup.count++))
  }, _toDisplayString($setup.count), 1 /* TEXT */))
}

↓ This is my compiled result, it use _ctx.count, has browser error : _ctx.count is undefined :

export function render(_ctx, _cache) {
  return (_openBlock(), _createElementBlock("button", {
    type: "button",
    onClick: _cache[0] || (_cache[0] = $event => (_ctx.count++))
  }, _toDisplayString(_ctx.count), 1 /* TEXT */))
}

↓ This is the file I use to compile in NodeJS, my parameter settings are like this :

import n_fs from 'fs';
import n_url from 'url';
import n_path from 'path';

const __filename = n_url.fileURLToPath(import.meta.url);
const __dirname = n_path.dirname(__filename);

import * as m_compiler from '@vue/compiler-sfc';

// read .vue file
let filePath = n_path.resolve(__dirname, './Counter.vue');
let fileContent = n_fs.readFileSync(filePath, 'utf8');
let fileName = n_path.parse(filePath).name;

function transformVueSFC(source, filename){
	
	let {descriptor, errors, } = m_compiler.parse(source, {filename:filename, });
	if(errors.length !== 0){ throw new Error(errors.toString()) };
	let id = Math.random().toString(36).slice(2, 12);
	
	let hasScoped = descriptor.styles.some(function(e){ return e.scoped });
	let scopeId = hasScoped ? `data-v-${id}` : undefined;
	let templateOptions = {
		filename : descriptor.filename,
		id : id,
		scoped : hasScoped,
		slotted : descriptor.slotted,
		source : descriptor.template.content,
		compilerOptions : {
			scopeId : hasScoped ? scopeId : undefined,
			mode : 'module',
		},
	};
	
	let script = m_compiler.compileScript(descriptor, {id, templateOptions, sourceMap:true, });
	console.log(script.content);
	
	let template = m_compiler.compileTemplate({...templateOptions, sourceMap:true, });
	console.log(template.code);
	
};

transformVueSFC(fileContent, fileName);

I know that this problem is not directly related to vue3-sfc-loader, but I found that vue3-sfc-loader can solve this problem, so I try to ask questions here. I have been troubled by this problem for two days. I tried to find a way to solve it myself, but there is not much content related to the compiler. I have searched for a long time for the information but could not solve it. I have begun to despair. I really hope that someone can help me , thank you so much. 😭😭😭
