I've install matplotlib in my virtualenv using pip. It was a failure at the beginning, but after I do easy_install -U distribute
, the installation goes smoothly.
Here is what I do (inside my git repository root folder):
virtualenv env
source env/bin/activate
pip install gunicorn
pip install numpy
easy_install -U distribute
pip install matplotlib
Then, I make a requirements.txt by using pip freeze > requirements.txt
. Here is the result:
argparse==1.2.1
distribute==0.7.3
gunicorn==17.5
matplotlib==1.3.0
nose==1.3.0
numpy==1.7.1
pyparsing==2.0.1
python-dateutil==2.1
six==1.3.0
tornado==3.1
wsgiref==0.1.2
Problem happened when I try to deploy my application:
(env)gofrendi@kirinThor:~/kokoropy$ git push -u heroku

The required version of distribute (>=0.6.28) is not available,
and can't be installed while this script is running. Please
install a more recent version first, using

Seems that heroku server can't install matplotlib correctly.
When I do easy_install -U distribute
it might not being recorded by pip.
Matplotlib also has several non-python-library dependencies (such as: libjpeg8-dev, libfreetype and libpng6-dev). I can install those dependencies locally (e.g: via apt-get
). However, this also not being recorded by pip.
So, my question is: how to correctly install matplotlib in heroku deployment server?
