#100335 — 2to3 translation problem

Debian Jessie, python 2.7; python 3.4

I have an application, using pygame for graphics, that works fine under 
python2.7. I have run it through 2to3, but when running the result under 
python 3.4, I get the error :

Traceback (most recent call last):
   File "ppm304.py", line 9, in <module>
     import pygame
ImportError: No module named 'pygame'

So, python 3.4 can't find the library, whilst python 2.7 can.
How do I track down/fix the missing dependency.

This isn't a 2to3 translation problem.  You've installed pygame under 
2.7 at some point, repeat the process for 3.4.  I've no idea how you'd 
do that on Debian Jessie but on Windows it'd be "pip3.4 install pygame".

Thanks, Mark, for the pointer. I'm pretty sure I installed Pygame from 
Debian's repository, via apt-get install python-pygame. I believe that 
should be effective for any version of Python.

Thanks anyway,
Tony

My belief is that every package has to be installed in the site-packages 
directory for each version of Python.

No, that is the version for Python 2. If there is a Python 3 version it will 
be called

python3-pygame

but no such package seems to be available:

https://packages.debian.org/search?suite=jessie&arch=any&searchon=names&keywords=python3-pygame

You are mistaken here.
python-pygame is only a python 2.7 pygame.

you want python3-pygame.
https://packages.debian.org/search?keywords=python3-pygame

Speaking as a debian user are going to have a _whole lot of this_.
If you don't know about apt-cache search <pkgname> 
let me recommend it to you.

This on debian unstable:

lac@smartwheels:~$  apt-cache search pygame
lightyears - single player real-time strategy game with steampunk sci-fi
psychopy - environment for creating psychology stimuli in Python
python-pygame - SDL bindings for games development in Python
python-pyglet - cross-platform windowing and multimedia library
pyntor - flexible and componentized presentation program
solarwolf - Collect the boxes and don't become mad
python-soya - high level 3D engine for Python
python-soya-dbg - high level 3D engine for Python - debug extension
python-soya-doc - high level 3D engine for Python
python3-pygame - SDL bindings for games development in Python (Python 3)

So, too many hits, alas, but it does tend to find such things.

Thanks, Laura, and others who have replied. You're right; 
python-3-pygame exists in unstable, but has not yet made it to jessie, 
even in backports.

So, I'll stick with python 2.7 for the time being; really no hardship :)

The easiest solution is simply:

python3 -m pip install pygame

Don't worry about it not being in the Jessie repo - you can always
grab things using pip.

What Chris said. :)

If you are about to move your life from being python2.7 based to 
being 3.x, you are not going to be able to depend on things getting
to jessie in a timely fashion.  So you will be doing this a whole lot.

No:
tony@tony-lx:~$ python3 -m pip install pygame
/usr/bin/python3: No module named pip

Hmm, apt-get install python3-pip: OK

tony@tony-lx:~$ python3 -m pip install pygame
Downloading/unpacking pygame
   Could not find any downloads that satisfy the requirement pygame
   Some externally hosted files were ignored (use --allow-external 
pygame to allow).
Cleaning up...
No distributions at all found for pygame
Storing debug log for failure in /home/tony/.pip/pip.log

I really can't be bothered...

Thanks for the hints.

Sorry, I forgot to warn you.  Debian, in its wisdom breaks python
up into several pieces, and so if you install python as a debian
package, you have to install the ability to use pip separately.

apt-get install python-pip  (for 2.x)
apt-get install python3-pip (for 3.x)

pygame itself was ported to 3.x years ago and the port is quite stable.
