vue-cli 运行 "npm run dev" 时如何解决跨环境问题

Question

当我运行npm run dev时，无法正常获取本地IP

Error: listen EFAULT: bad address in system call argument 0.0.0.0:8081

我愿意。
1.删除"cross-env"文件夹和node_modules
下的"cross-spawn"文件夹 2. 运行 npm install
3. 运行 npm run dev
4.报错ip变化如下

Error: listen EFAULT: bad address in system call argument 10.0.75.1:8081

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;
             ^

如果你试试这个会怎样：

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

或使用 npm 代替 yarn
