package.json 脚本命令

新增自定义变量：VUE_APP_API_ENV

"build:app-plus-sit": "cross-env NODE_ENV=production UNI_PLATFORM=app-plus VUE_APP_API_ENV=sit vue-cli-service uni-build"

操作步骤：

如上代码，新增多个打包环境命令自定义变量 VUE_APP_API_ENV=sit
在vue和nvue中打印process.env.VUE_APP_API_ENV

预期结果：

预期都能打印出”sit“

实际结果：

vue页面可以打印出”sit“
nvue页面打印出”undefined“
