关于vue.js:vue项目多环境配置env的实现

 "scripts": {    "serve": "vue-cli-service serve",    "build": "vue-cli-service build",    "build:bsy": "vue-cli-service build --mode bsy",    "build:kthz": "vue-cli-service build --mode kthz",    "serve:bsy": "vue-cli-service serve --mode bsy",    "serve:kthz": "vue-cli-service serve --mode kthz",  },

--mode bsy 对应.env.bsy 文件，其余模式相似，如--mode kthz 对应.env.kthz 文件
