error while patching APK

Hi,

i got an error when I tried to patch the APK. Maybe you can help: 

"An error occured: command'[venvscriptbuildapp','-d','tappedout',/-o','the-simpsons-tapped-out-4-69-5-patched.apk']' returned non-zero exit status 1." 

i dont know what to do, searched for it, but it seems that noone has this error. until this step, everything went smoothly.

thank you
