i appreciated if guys can help. i'm depressed right now...

you need add requirements.txt file contains of modules required run application.

you can pip freeze > requirements.txt freeze of modules file. recommend doing if you're using virtualenv because otherwise add of modules.

anyways, determine modules application requires , create file called requirements.txt , put in application directory.

the syntax requirements file follows:

package name == version # package name == version # package name == version # 

note: optional specify version number.

here example requirements file (taken this tutorial):

flask==0.11 jinja2==2.8 gunicorn==19.6.0 

don't forget commit requirements.txt
