使用sencha命令生成extjs6应用程序时获取帮助消息

我安装了Snecha并下载了Extjs6

sencha -sdk home/apps/ext-6.0.1 generate app loginapp6 /home/Senchaapplications/loginapp6

则输出为:

Sencha Cmd v6.2.0.103
Sencha Cmd provides several categories of commands and some global switches. In
most cases, the first step is to generate an application based on a Sencha SDK
such as Ext JS or Sencha Touch:

    sencha -sdk /path/to/sdk generate app MyApp /path/to/myapp

Sencha Cmd supports Ext JS 4.1.1a and higher and Sencha Touch 2.1 and higher.

To get help on commands use the help command:

    sencha help generate app

For more information on using Sencha Cmd, consult the guides found here:
