Python3 and Pyglet - help needed

Question

I am a newbie of Python and Pyglet. I just installed Pyglet on my Linux and Window7. I run a very simple test file on my Linux, I got errors

(On linux: Python 3.5.2 Pyglet 1.2.4)

The following is the test file-tests.py:

import pyglet

window = pyglet.window.Window()
pyglet.app.run()

I got the following errors when I run it on my Linux:

Traceback (most recent call last):

File "/home/work/.local/lib/python3.5/site-packages/pyglet/init.py", line 351, in getattr return getattr(self._module, name)

AttributeError: 'NoneType' object has no attribute 'Window'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "test.py", line 6, in <module> window = pyglet.window.Window() File "/home/work/.local/lib/python3.5/site-packages/pyglet/init.py", line 357, in getattr import(import_name)

pyglet.window.xlib.XlibException: Could not create UTF8 text property*

This test file works ok on my Win7

(On Window7: Python 3.6.0 Pyglet 1.2.4)

Please help if you know why. Thanks.

Answer 1

As we figured out from the comments above, it looked like the installation output printed some odd symbols. That and the fact that pyglet had problem loading UTF-8 context lead me to believe that there were no UTF-8 support generated in the OS.

Usually, you can uncomment en_US.UTF-8 in /etc/locale.conf and run locale-gen and that should solve the problem.

Answer 2

in your terminal

1. write LANG=en_US
2. Run your python code from the terminal

another solution by placing it before everything of your code

import os
os.environ['LANG']='en_US'

Answer 3

1. edit your /etc/default/locale, and try to feed all locale critiria as the same:

#  File generated by update-locale
LANG=en_US.UTF-8
LC_NUMERIC=en_US.UTF-8
LC_TIME=en_US.UTF-8
LC_MONETARY=en_US.UTF-8
LC_PAPER=en_US.UTF-8
LC_NAME=en_US.UTF-8
LC_ADDRESS=en_US.UTF-8
LC_TELEPHONE=en_US.UTF-8
LC_MEASUREMENT=en_US.UTF-8
LC_IDENTIFICATION=en_US.UTF-8
LC_ALL=en_US.UTF-8

1. Use sudo dpkg-reconfigure locales to set your own language. Make sure to mark en_US.UTF-8 selection.
2. sudo locale-gen en_US en_US.UTF-8
3. Reboot
