vue路由报错export ‘default‘ (imported as ‘VueRouter‘) was not found in ‘vue-router‘

报错信息：

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

问题分析：

vue版本和vue-router版本不兼容

我这里是用vue cli脚手架构建的vue2项目，安装的路由版本是4

解决办法：

 卸载这个不兼容的路由版本，重新安装对应的版本：

npm uninstall vue-router

安装3版本：

npm install [email protected]

最好就不会报错了。

• vue2搭配vue-router3
•  vue3搭配vue-router4
