生成Sencha Touch 2 app nullpointer错误

Question

我正在尝试使用以下内容生成新应用:

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

但是,我得到以下内容:

    Sencha Cmd v4.0.1.4
    [INF] Workspace does not have framework touch at /var/www ... copying
[ERR] java.lang.NullPointerException
     at com.sencha.util.Version.<init>(Version.java:36)

令人困惑的是我之前已经生成了应用程序.我不知道为什么我创造新的尝试失败了.

注意:

我尝试升级Sencha但它似乎确实具有欲望效果,如下所示:

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

更新:

我试图从TOUCH文件夹外部生成应用程序,但我得到一个关于SampleApp已经存在的奇怪错误.我在目标目录中没有任何名为SampleApp的内容.数据如下:

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 1

感谢arthurakay和Anand Gupta的投入和尝试帮助,我最终找到了问题所在.

发生的事情是在某些时候我通过尝试在同一个i:e/var/www目录中生成一个sencha应用程序来破坏我的/ var/www目录.这是造成所有破坏的错误.

幸运的是,我碰巧列出了所有隐藏文件并找到了一个.sencha文件夹,这就是为什么它一直在抱怨SampleApp,如我的问题的更新部分所述.

一旦我删除了.sencha文件夹和其他相关数据,事情就会超越其他挑战.

再次感谢您的所有意见.
