Re: compiling matplotlib in virtual env

2015-10-02 Thread bayang

I ran into the same issue.
Check here
http://stackoverflow.com/questions/27024731/matplotlib-compilation-error-typeerror-unorderable-types-str-int
It worked for me on python 3 with virtualenv in ubuntu .  Libfreetype was
missing.

Use pillow rather than PIL.  API is same.  Don't know about rest of 
your question.



anything. Is there another way to install those dependencies?

But more importantly: can I develop with python3 for the Android?
Because the primary reason to use Kivy is to develop applications for 
Android.






Got the same issue a few days ago with python3.
Installed pygame dependencies, installed pygame, installed pillow and 
everything went fine (using pip in virtualenv)

I see a difference with python2. (Did not notice it before.) With
python3 v1.9.0 is installed, but with python2 v1.8.0.
 [INFO  ] Kivy v1.8.0

Maybe that is the problem?


Pygame doesn't seem to be correctly installed.
check this : http://www.pygame.org/wiki/CompileUbuntu#Python_3.x
in "installing pygame with pip" part.
Install dependencies first, then
pip install hg+http://bitbucket.org/pygame/pygame
