Question

我正在尝试使用ionic 2命令为ionic serve应用程序提供服务，但我收到错误消息：

$ ionic serve
******************************************************
 Dependency warning - for the CLI to run correctly,
 it is highly recommended to install/upgrade the following:

 Please update your Cordova CLI to version  >=4.2.0 `npm install -g cordova`

正在运行的版本：

离子版：2.2.1

Cordova版本：6.5.0

npm版本：3.10.10

节点版本：6.9.5

我使用ionic start myApp tabs --v2创建了项目。

在ionic2中产生UNKNOWN错误
