【Vue Laravel-mix】Error with Vue lazy loading components: “Failed to resolve async component“

【Vue Laravel-mix】
报错信息：
Error with Vue lazy loading components: “Failed to resolve async component“
uncaught error during route navigation
cann’t xxxxx 'call ’
bootstrap.js(63)

参考https://github.com/JeffreyWay/laravel-mix/issues/2064 中所有的解决方法，均没有修改功能

失败方案：

方法一：删除每个vue文件中的style标签及其内容，结果删除所有style标签之后，仍报错（失败）

方法二：降级 laravel-mix: ^3.0 ，结果会产生css-loader 找不到等其他的错误（失败）

方法三：chunk文件，即在 webpack.mix.js 文件中 output.chunkFilename: 'js/chunk/[name].js?v=[chunkHash]'，仍旧报错（失败）

 mix.webpackConfig(
        output: {
            publicPath: '/', // 不加会报语法错误
            chunkFilename: 'js/chunk/[name].js?v=[chunkHash]' // 分割文件存放位置， 
        }
    })

方法四：添加异步加载插件@babel/plugin-syntax-dynamic-import，

方法四-1与 方法四-2 本质是一样的，只是配置方式不一样哈

方法四-1：

npm install -D @babel/plugin-syntax-dynamic-import

# webpack.mix.js
mix.babelConfig({
    plugins: [
        '@babel/plugin-syntax-dynamic-import'
    ]
});

方法四-2：

# babel.rc
{
  "presets": [
    "@vue/babel-preset-jsx",
    "@babel/preset-env"
  ],
  "plugins": [
    "@babel/plugin-syntax-dynamic-import"
  ]
}

# 父组件：

    <child></child>
</template>
<script>
报错方式：
import child from "../components/child";
export default {
  components: {
    child,
  },
}

运行正常方式：
export default {
  components: {
    child: ()=>import("../components/child"),
  },
}
</script>
