Vue执行报错“export ‘computed‘ was not found in ‘vue‘

后来发现vue-router版本太高了，不适用于Vue2，只需要删除vue-router，然后重新安装指定版本就可以了。时报如下错误，啥都找不到，这时候前面的Element-UI啥的都装好了，这里只装了一个vue-router后就这样了。

Vue再执行npm run serve时报如下错误，啥都找不到，这时候前面的Element-UI啥的都装好了，这里只装了一个vue-router后就这样了。

后来发现vue-router版本太高了，不适用于Vue2，只需要删除vue-router，然后重新安装指定版本就可以了。

npm uninstall vue-router
npm install vue-router@3.5.2
