My Kivy Virtualenv Install Scripts

[Ben Rousch]

I know a few of you are using the scripts from my Gists for installing Kivy into a virtualenv on Ubuntu and Debian, so I wanted to let you know that I've recently updated them. I fixed a bug with the python-gst version, added code to remove some common newbie conflicts (system cython, old system pip and virtualenv), included a few more commonly-needed packages (Java, git), added comments, and automated some of the other commands.

Please note that these are not the official Kivy install instructions, but I find them very useful on my systems with multiple Kivy and python-for-android projects.

Also note that they remove some packages without asking, so make sure you read through the script and understand what it does.

To use the scripts:

  1. git clone the gist

  2. cd to your project root

  3. Run the bash script in the cloned gist from your project root

  4. Activate the new virtualenv (source venv/bin/activate)

  5. Initialize buildozer.spec (buildozer init)

  6. Now you have a Kivy project ready to use!

Please report any bugs to me, and feel free to fork these scripts and modify them to suit your own development preferences.

great!

This is very nice!

One question, if I wanted to setup a python3.3 + kivy1.8 environment,, can I just change

virtualenv -p python2.7 venv

to

virtualenv -p python3.3 venv

and add python3.3 to the system packages in the first line?

Thank you!!|

I have a Python3 dev version at https://gist.github.com/brousch/8426921

Some of the system packages are different, and the Python3 version doesn't have the py4a stuff since that does not yet support Python3. I should take another look at this now that 1.8 is stable.

Something went wrong during the installation.

Thanks for any help

That looks like a file failed to download. You should try stepping through the script manually line-by-line to see when the failure occurs.

Hi Ben and thanks for your help.
I did try it line by line.

. 

I noticed in my environment (Ubuntu 13.04 ) the call

virtualenv-3.3 venv
fails, seems like virtualenv does not install its virtualenv-3.3 version
I tried using 
virtualenv-3.3 -p /usr/bin/python3.3 venv 
which seems to work.

But then I get a

Error compiling Cython file:

---

...

from transformation cimport Matrix
from instructions cimport ContextInstruction
from texture cimport Texture

cdef class PushState(ContextInstruction):
^

---

kivy/graphics/context_instructions.pxd:9:5: Compiler crash in AnalyseDeclarationsTransform

I set up an Ubuntu 13.04 (which is apparently out of support already) virtual machine. It looks like virtualenv for Python3.3 is installed as 'virtualenv' on Ubuntu 13.04, even though the system Python is Python2.7. Weird, but weirdness like that is why I work from LTS.

Anyways, I changed line 20 in the script to:
virtualenv venv
And it worked. I didn't have any problems with cython compilation. However this VM is 32bit as I don't have 64bit VM capabilities, so there could still be a problem with 64bit that I don't know about.

Also I did find a problem later in the script when Kivy is actually installed. It was using my clone of the Kivy repository instead of the official one. I have fixed that problem just now.

[Sergio Marchesini]

That's great, thank you Ben so much for your help.
Will try it and let you know.

Appreciate.

Works fine, but for Ubuntu 13.10 i had to replace 

sudo pip-2.7 install -U virtualenv

with

sudo pip2.7 install -U virtualenv

Don't know if it's a bug or just for ubuntu 13.10.

Thanks anyways!
