使用webpack 搭建 vue，遇到这个问题：
Cannot find element: #app
解决办法：
1，根目录public，新建html
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title><%= htmlWebpackPlugin.options.title %></title>
</head>
<body>
<div id="app"></div>
</body>
</html>
2，webpack.config.js
...
plugins: [
new HtmlWebpackPlugin({
title: "webpack & vue",
template: "./public/index.html",
}),
],
...
