From the appcelerator studio I selected file -> new -> mobile app project. The open dialog appears but does not display the option to create an alloy app. These are the only options I can see in New mobile app project dialog box
Thanks in advance.
Seems Alloy was not installed in your system for any reason which is quite odd. But here you can install it using command-line/terminal by running this command :
sudo npm install -g alloy
After successfully installing Alloy, you can check for its version using below command:
appc -v
mine is Alloy version 1.10.7
You can also check for Alloy installation in your Studio About section as shown in screenshot.
Select About Axway Appcelerator Studio -> Installation Details -> Plug-ins
