webpack5启动项目报错：process is not defined

1.安装dotenv-webpack@8.1.0插件

2.在vue.config.js中配置

const Dotenv = require("dotenv-webpack")
const env = process.env.NODE_ENV || "development"plugins: [new DefinePlugin({}),new HtmlWebpackPlugin({template: path.resolve(__dirname, 'public/index.html'),filename: "index.html",templateParameters: {BASE_URL: `/`},}),//配置环境变量文件地址new Dotenv({path: `./.env.${env}`}),],

3.新建.env.development、.env.production文件

# just a flag
NODE_ENV = 'development'
STAGE = 'demo'
# LOCAL_URL = 'http://121.5.74.20/meapi/'# default port
port = 3001# base api
VUE_APP_BASE_API = '/apii'
# http://10.100.2.94:9011# debugger modal
VUE_APP_DEBUG = false

4.所有webpack5+vue2对应的插件及版本
