vue 服务端渲染开发框架搭建问题

Question

我在使用webpack搭建一个vue服务端渲染的工程，出现了一个问题，我搭建的是多页面开发环境，admin和project两个页面，当我使用webpack打包的时候vue-server-renderer中间件的createRenderer方法返回的html中自动注入了包含admin和project两个页面的js和css，不知道是为什么。麻烦给予帮助，非常感谢。

}

最后我启动服务以后 通过http://localhost:8080/project访问project页面，给我返回的HTML是这样的 包含了admin的js和css

求大神给予帮助。非常非常非常感谢。
