【问题描述】：
我使用 Vue cli 创建了一个 vue 3 项目。我正在使用 webpack 配置来管理我的构建。当我将我的 vue 包指向 vue.runtime.esm-browser.js 时，我会在浏览器控制台中收到警告。 “[Vue 警告]：组件提供的模板选项，但此 Vue 版本不支持运行时编译。请改用“vue.esm-browser.js”。”
当我查看文档时，提到“vue-loader”插件将 html 模板转换为渲染函数。看起来我缺少 webpack 所需的东西。
入口文件：main.js
import { createApp } from "vue";
import corecomponentA from "../core/components/corecomponentA.vue";
createApp({
components: {
"core-component-a": corecomponentA,
},
}).mount("#app");

const BundleAnalyzerPlugin = require("webpack-bundle-analyzer")
.BundleAnalyzerPlugin;
const WebpackBar = require("webpackbar");
module.exports = (env, options) => {
const devMode = options.mode != "production";

在 html 文件中使用我的组件
<div id="app">
<core-component-a></core-component-a>
</div>
组件未在浏览器中呈现。而是显示以下消息。
VM211871:1 [Vue warn]: Component provided template option but runtime compilation is not supported in this build of Vue. Use "vue.esm-browser.js" instead.
at <App>
