Linux：无法在虚拟环境中安装kivy

Question

I am using python2.7 and created a virtual environment 'kivyenv'. First i install Cython and then kivy in kivyenv.

pip install Cython
pip install kivy

kivy failed to install giving some error :-

In file included from /tmp/pip-build-4T9oG4/kivy/kivy/graphics/opengl.c:274:0:
/tmp/pip-build-4T9oG4/kivy/kivy/graphics/gl_redirect.h:43:22: fatal error: GL/gl.h: No such file or directory
 #   include <GL/gl.h>
                      ^
compilation terminated.
 error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

----------------------------------------
Command "/root/kivyenv/bin/python2.7 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-4T9oG4/kivy/setup.py';
exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))"

 /root/kivyenv/include/site/python2.7/kivy" failed with error code 1 in /tmp/pip-build-4T9oG4/kivy/

I am using Ubuntu 16.

Answer 1

This is happening because you do not have dependency libraries installed on your system, specifically the ones for OpenGL - most likely you do not have mesa packages installed.

Follow the instructions for your specific distribution on how to install all of the needed dependencies at: https://kivy.org/docs/installation/installation-linux.html#using-software-packages

Answer 2

had the same problem. the following worked for me:

pip(3) install Cython==0.26

pip(3) install kivy

hope it helps
