I issued this command:
sencha generate app LaBucaDiSanMatteo c:\xampp\htdocs\LaBucaDiSanMatteo
from inside SDK folder (c:\touch-2.3.1).
I got: [INF] Workspace does not have framework null at C:\xampp\htdocs\LaBucaDiSanMatteo ... copying [ERR] Failed to determine framework name. Please ensure this command was issued from either a framework or application directory
I'm using Sencha Cmd v4.0.2.67
