I know it's weird to reply to myself, but just in case that somebody has
the same problem.
It seems that the problem it is in the requirements.txt, i created it using
powershell and "pip.exe freeze > requirements.txt" command,
which creates a file with a name that has nullbytes in it.
I was able to get around this problem by downloading a requirements.txt
from an example project on github and modifying it.
That did the job and everything works nice.
