"Install dependencies with pip" exception when deploy flask project to Heroku

I was trying to deploy a simple app to heroku using git push heroku master, then I got the following error:

$git push heroku master

I guess there might be some version inconsistence, but cannot figure out which one it is. Here is my requirements.txt:

-e git+http://github.com/mitsuhiko/flask.git@577581665ce745898c29ca502e0a3aba1f16677e#egg=Flask-origin/HEAD
Jinja2==2.7.3
MarkupSafe==0.18
Werkzeug==0.9.6
click==2.4
gunicorn==19.0.0
itsdangerous==0.24
wsgiref==0.1.2

This is my first post here, so if anything doesn't look good, pls let me know. Thanks a lot~!

Remove the -origin/HEAD part from git+http://github.com/mitsuhiko/flask.git@577581665ce745898c29ca502e0a3aba1f16677e#egg=Flask-origin/HEAD:

-e git+http://github.com/mitsuhiko/flask.git@577581665ce745898c29ca502e0a3aba1f16677e#egg=Flask
Jinja2==2.7.3
MarkupSafe==0.18
Werkzeug==0.9.6
click==2.4
gunicorn==19.0.0
itsdangerous==0.24
wsgiref==0.1.2

When using VCS the text after #egg= has to be a valid requirement specifier, the same format as when specifying packages directly:

The url suffix "egg=<project name>" is used by pip in it’s dependency logic to identify the project prior to pip downloading and analyzing the metadata.
