Cocos 2dx v3.0 error when create new project "Can't find '_main_' in module 'cocos'".

Hi all!

I have a problem with Cocos2dx v3 rc0

I set all Environment OK
build android project by run “Python android-build.py -p 10 cpp-tests” OK

But when I run commend

“python cocos” or create new project “python cocos new MyGame -p com.your_company.mygame -l cpp -d /home”, getting error

“Can’t find ‘main’ in module ‘cocos’”.

How to fix it?
