I am attempting to install kivy in a virtualenv, following the official instructions. However, when I run pip install kivy I get the following error (full traceback and steps to reproduce below). I am running Ubuntu 16.04 LTS 'Xenial'. Where should config.pxi come from, and what should it contain? Am I missing an installation step, or is this due to an assumption in Kivy's setup.py?

   [...]
   File "/home/vagrant/.virtualenvs/kivy/local/lib/python2.7/site-packages/Cython/Build/Dependencies.py", line 474, in included_files
     include_path = self.context.find_include_file(include, None)
   File "/home/vagrant/.virtualenvs/kivy/local/lib/python2.7/site-packages/Cython/Compiler/Main.py", line 274, in find_include_file
     error(pos, "'%s' not found" % filename)
   File "/home/vagrant/.virtualenvs/kivy/local/lib/python2.7/site-packages/Cython/Compiler/Errors.py", line 177, in error
     raise InternalError(message)
 Cython.Compiler.Errors.InternalError: Internal compiler error: '../include/config.pxi' not found

The installation process looks for config.pxi in these locations:

  • /tmp/pip-build-MB2bZR/include/config.pxi
  • /home/vagrant/.virtualenvs/kivy/local/lib/python2.7/site-packages/Cython/include/config.pxi

Investigation

The problem is consistent across versions

The problem occurs both with pip install kivy==1.10.0 and with pip install git+https://github.com/kivy/kivy.git@master.

Execution context:

The problem occurs in find_include_file in Cython 0.25's Main.py.

Steps to reproduce

Because the steps to reproduce include sudo apt-get install, I have placed
them in a Vagrantfile. Vagrant makes it trivial to create and destroy virtual
machines that have the same environment every time. This is useful for
reproducible development environments, but also to demonstrate bugs.

If you do not want to use Vagrant, look for the code below.

  config.vm.provision "shell", inline: <<-SHELL
    # ... this is the code you need ...
  SHELL

Vagrant usage

  • Install Vagrant from https://www.vagrantup.com
  • Create a directory, and place the contents below in a file called Vagrantfile
  • cd to the directory and run vagrant up
  • The problem mentioned above will occur at the end of the provisioning.
  • You can use vagrant ssh to SSH into the virtual machine
  • You can use vagrant destroy + vagrant up to recreate the machine from scratch

Vagrantfile

Call this file Vagrantfile. See the previous section for usage.

# -*- mode: ruby -*-
# vi: set ft=ruby :

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for

Vagrant.configure("2") do |config|

  config.vm.box = "bento/ubuntu-16.04"

  config.vm.synced_folder "data", "/vagrant_data"

  config.vm.provision "shell", inline: <<-SHELL
