Generating Sencha Touch 2 app nullpointer error

I’m trying to generate a new app using the following:

root@li184-76:/var/www/touch-2.3.1# sencha generate app NewApp ../newapp

However, I get the following:

    Sencha Cmd v4.0.1.4

The confusing thing is I already have previously generated apps. I don’t know why my attempts to create new ones are failing.

NOTE:

I tried upgrading Sencha but it does seems to have the desire effect as the following shows:

root@li184-76:/var/www/touch-2.3.1# sencha upgrade
Sencha Cmd v4.0.1.45
[INF] Determining the latest version of Sencha Cmd
[INF] The latest version of Sencha Cmd is 4.0.2.67
[INF] Sencha Cmd 4.0.2.67 is already installed

UPDATE:

I attempted to generate the app from outside the TOUCH folder but I get a weird error about SampleApp already existing. I have nothing called SampleApp in the target directory. The data is as follows:

root@li184-76:/var/www# sencha -sdk /var/www/touch-2.3.1/ generate app MyApp /var/www/myapp
Sencha Cmd v4.0.1.45
[ERR] Path /var/www/myapp is already a configured application named : SampleApp
[ERR] Path /var/www/myapp is already configured for application SampleApp
root@li184-76:/var/www#

Answer

With thanks to arthurakay and Anand Gupta for your input and attempts to help, I eventually figured out the problem.

What had happened was at some point I corrupted my /var/www directory by attempting to generate a sencha app in the same, i:e /var/www, directory. That was the mistake that was causing all the havoc.

Luckily, I happened to list all the hidden files and found a .sencha folder which is why it kept complaining about SampleApp as described in the update section of my question.

Once I removed the .sencha folder and other related data, things moved beyond this to other challenges.

Thanks again for all your input.
