Can you provide more information?

[hhirsch]

I just installed by pip and launched plover and all I got was this trace. I am on Debian 7 on xmonad. The trace seems to indicate that there was a problem launching uname as a child process. And when I try running uname -p I get unknown. Maybe that normal and documented behaviour is considered exceptional by platform.py. But I am just throwing spaghetti at the wall seeing what sticks. Thank you for looking into this and tell me if you need more information and I go probe my system.

[hhirsch]

When following http://openstenoproject.github.io/plover/ I get the same error.

[balshetzer]

The version of Plover that is installed by pip is very old. Also, installing Plover with pip doesn't install its dependencies.

I see you found the newer instructions. I assume you downloaded the new code, installed all the specified dependencies and still get the error?

[hhirsch]

Yes, only difference is that the message is displayed in a gtk window.

[balshetzer]

Can you find out which version of python2.7 you're using?

[hhirsch]

Python 2.7.3

[balshetzer]

One thing we could try is updating to a newer version. It goes up to 2.7.9 now.

[hhirsch]

It works with my work PC with the same OS and python.

[balshetzer]

Can you think of some way in which the two computers are different?

[hhirsch]

No, I assumed we could get insights from the trace.

[hhirsch]

I commented out Line 1273 and the next.

if not processor:

    # Get processor information from the uname system command  
    # processor = _syscmd_uname('-p','') 

In /usr/lib/python2.7/platform.py and now plover starts.

Can you check if your platform.py is different there?

[balshetzer]

I downloaded the source for Python 2.7.3 and it does not match. I'm not sure what that means.

A simpler thing to test would be to restore your platform.py to its original form, open a console and enter: import platform; platform.uname()

Does it throw an exception?

[hhirsch]

I assume this issue has nothing to do with plover. I will re-open it if I have reason to assume it is plovers fault.
