关于 ant-design/babel-plugin-import 按需加载的 babel polyfill疑问。

Question

问题

在项目新建的时候引用了babel-plugin-import的antd按需加载plugin，已配置好相关的babel-preset，但是在实际webpack输出的bundle内发现，按需加载的antd源码并没有被polyfill。

尝试方法（均无效）

• 将ant-design-vue提升到devDependencies
• 将ant-design-vue的包include到babel-loader中

环境

babel-loader配置如下：

            {
                test: /(\.jsx|\.js)$/,
                loader: "babel-loader",
                // exclude: path.resolve(__dirname, "node_modules")
                include: [path.resolve(__dirname, "xxx/src"), path.resolve(__dirname, "node_modules/ant-design-vue")]
            }

.babelrc配置如下：

{
    "presets": [
        [
            "@babel/preset-env",
            {
                "modules": "commonjs",
                "targets": [
                    "> 1%",
                    "last 2 versions",
                    "ie 11"
                ],
                "useBuiltIns": "usage",
                "corejs": 3
            }
        ]
    ],
    "plugins": [
        [
            "import",
            {
                "libraryName": "ant-design-vue",
                "style": true
            }
        ]
    ]
}
