Ionic2 start app error: Error with start undefined

   This problem is solved by using the Taobao image。

    Install Taobao image

    E:>npm install -g cnpm --registry=https://registry.npm.taobao.org

    First：Skip NPM installation
    
    E:>ionic start mobileapp blank --v2 --skip-npm
    
    Second:

    E:\mobileapp>cnpm install

    
    ## In this way can be installed successfully, but the NPM folder file structure and NPM installation is very different.
