ionic2 The --v1 and --v2 flags have been removed.

Posted 2020-10-21 风起时的悟

安装ionic2后，新建项目时出现了如题错误

>ionic start MyIonic2Project tutorial --v2
[ERROR] Sorry! The --v1 and --v2 flags have been removed.

        Use the --type option. (ionic start --help)

        For Ionic Angular projects, try ionic start MyIonic2Project tutorial --type=ionic-angular

命令提示v1和v2命令没有了，应该是我看的教程不是最新的原因。去官网一看才知，人家默认生成的是ionic2的项目，如果是1的话需要加上--type=ionic1 命令。而我看的教程上说的是默认生成v1的项目。还是以官网为准啊。

解决:

> ionic start cutePuppyPics

　然后出现以下内容就是ok了

c>ionic start cutePuppyPics

期间会弹出几个供你选项 的提示：

1、? What starter would you like to use:

• tabs：一个简单的3选项卡布局
• sidemenu：一个带有菜单边的布局
• blank：一个带有单一页面的裸启动器
• super*启动项目，有14多个准备使用页面设计
• tutorial*一个引导启动项目

　　我选的是sidemenu，官方上给的就是这个。

2、? Would you like to integrate your new app with Cordova to target native iOS and Android? 

您想将您的新应用程序与cordova集成到本地ios和android吗？YES

3、Install the free Ionic Pro SDK and connect your app?

是不是安装Pro版帮助你开发？  (NO) ^_^这就看你了 输入yes的话会让你登录什么的

然后进入项目目录，执行 ionic serve

>ionic serve
