报错内容

export 'default' (imported as 'VueRouter') was not found in 'vue-router' 
(possible exports: NavigationFailureType, RouterLink, RouterView, START_LOCATION, createMemoryHistory, 
createRouter, createRouterMatcher, createWebHashHistory, createWebHistory, isNavigationFailure, matchedRouteKey, 
onBeforeRouteLeave, onBeforeRouteUpdate, parseQuery, routeLocationKey, routerKey, routerViewLocationKey, 
stringifyQuery, useLink, useRoute, useRouter, viewDepthKey)

解决方法

发现默认npm i vue-router -S 安装,vue-router安装为最新版本@4.0.13，版本太高。

npm uninstall vue-router -S //卸载最新版本

npm i vue-router@3.5.1 -S //安装旧版本

问题解决，如有不对之处，请大佬指出
