This is a much needed solution to a problem that has been plaguing my development cycle for weeks. Many "thankyous", stranger.

Thanks Brian! The out-file command with ascii encoding specified fixed this for me.

Thanks John, that was useful.
This happens because powershell outputs UTF-16 by default. Another way to fix it is by using the out-file command with an ascii encoding specified:

pip freeze | out-file -enc ascii requirements.txt

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.

Hi. I want to deploy a Django project on Heroku. The logic it's straightforward : create a virtualenv, install django, some other stuff, pip freeze into requirements.txt, create a git repository and git push it to project's repository. From what i've seen it seems like the service downloads the project and install virtualenv and pip on virtual server and it uses pip to install dependencies listed in requirments.txt . While pushing to remote server it looks like everything goes nicely until pip starts to install dependencies and then a error happens. I'm new to pip so maybe someone already seen this error. Thank you in advance.
