Hi I am trying to learn and getting started with ExtJS (from here). but seems either I am missing something, or bugged by some issue here. Whenever I am trying to execute first basic simple command: sencha generate app -ext Myapp ./app its failed with below exceptions:

Sencha Cmd v5.0.0.160

When I am trying to execute sencha generate app MyApp ./app is throws below exception:

Sencha Cmd v5.0.0.160 
[ERR] Unable to locate 'framework.dir' property from sencha.cfg and no framework directory specified
[ERR] Please ensure this command was executed from a valid framework directory
[ERR] No Framework specified

What is framework.dir here ? I have downloaded Sencha ExtJS v5.0.0 as well, do I need to keep it somewhere ?

Update
After running sencha -sdk /path/to/extjs-5.0.0 generate app MyApp ./app giving same result, saying repo is not initialized properly.

I have installed both Ruby v1.9.3 and Sencha Cmd v5.0.0.160 which you can see on top of exception above. any idea how to resolve this ?

You must either run Sencha Cmd from the directory where you installed ext or you must give it path to where Ext is installed.

This should work:

sencha -sdk /path/to/ext/ generate app MyApp /where/you/want/the/app

  • Something very weird, I had no choice than hard reset/format my desktop machine !! :( **after that everything working smoothly..!!** if any one knows the exact root cause, please share it. – Aman Gupta Jun 18 '14 at 10:01

To avoid any confusion just pass full path of "sencha cmd", "sencha sdk" and your desired application target directory.

Like 

/Users/vishnu/bin/Sencha/Cmd/5.1.0.26/sencha -sdk /Users/vishnu/Documents/senchaworkspace/ext-5.0.1 generate app TutorialApp /Users/vishnu/Documents/senchaworkspace/TutorialApp

This works for me perfectly

  • Yes You are right. There was some weird issue with my machine, I had to hard reset it in order to get it worked properly. – Aman Gupta Dec 27 '14 at 15:27
