Vue 去脚手架插件，自动加载vue文件，style怎么办

// vue插件引入
Vue.use({
    // 插件初始化函数
    install: function(Vue, options) {
        Vue.CptsLoader = {
            isSaveTemplateToLocalStorage: false,
            ProjectVersion: "1.0.0.0",
            checkVersion: function() {
                var ver = localStorage.getItem(window.location.href + ‘ProjectVersion‘)
                if(!ver || this.ProjectVersion !== ver) {
                    localStorage.clear()
                    localStorage.setItem(window.location.href + ‘ProjectVersion‘, this.ProjectVersion)
                }
            }
        }
        // 包装new Vue()
        Vue.create = function(options) {
            Vue.CptsLoader.checkVersion()
            // 加载options的components
            importCpts(options)
            var vm = new Vue(options)
            Vue.http.options.emulateJSON = true
            return vm
        }
        Vue.loadvue = function(options) {
