我有一个完整的堆栈应用程序，其中Vue运行webpack-dev-server，而节点运行在express上。
我的webpack-dev-server配置为在port 8080上打开Vue，并在port 8081上进行快速侦听。
但是，即使我的Webpack配置如下，我的Vue应用程序最近也开始默认在port 8081上运行。
webpack.dev.config.js
const HOST = process.env.HOST
const PORT = process.env.PORT && Number(process.env.PORT)
Vue配置为
config / index.js
host: 'localhost',
port: 8080,
