如何为vue-cli运行“npm run dev”时修复跨环境问题

Question

当我运行npm run dev ，我无法正确获取本地IP。

错误：侦听EFAULT：系统调用参数0.0.0.0:8081中的错误地址

我做。
1.删​​除node_modules下的“cross-env”文件夹和“cross-spawn”文件夹
2.运行npm install
3.运行npm run dev
4.错误ip改变如下。

错误：侦听EFAULT：系统调用参数10.0.75.1:8081中的错误地址

ip地址是docker的vEthernet。

PS E:\WorkSpace\my-project> npm run dev

> my-project@1.0.0 dev E:\WorkSpace\my-project
> cross-env NODE_ENV=development webpack-dev-server --open --hot

E:\WorkSpace\my-project\node_modules\webpack-dev-server\bin\webpack-dev-server.js:356
    if (err) throw err;
             ^

如果您尝试这样做怎么办：

yarn remove webpack-dev-server
yarn add webpack-dev-server@2.9.1 --dev
yarn run dev

或使用npm代替纱线
