问题描述 Problem Description
首先很感谢作者提供library！
vue-request 从2.0.0-rc.4版本更新到 2.0.1之后 webpack打包出现错误。
项目环境：项目是用vue-cli-service搭建的， 项目携带的webpack版本是4.46.0。
安装2.0.1打包时报错信息：
Failed to compile with 1 error 12:15:31 PM
error in ./node_modules/vue-request/dist/index.es.js
Module parse failed: Unexpected token (23:40)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
| const isServer = typeof window === 'undefined';
| const isDocumentVisibility = () => {
> if (isServer || isNil(window.document?.visibilityState)) return true;
| return window.document.visibilityState === 'visible';
| };
@ ./src/main.js 12:18-40
@ multi (webpack)-dev-server/client?http://192.168.0.78:1024&sockPath=/sockjs-node (webpack)/hot/dev-server.js ./src/main.js
如果使用2.0.0-rc.4则不会报错。
我对比了一下2个版本的同一行代码，问题应该出现在webpack无法解析 optional chaining: ?.
请问一下是因为我的webpack版本太老导致的吗？
