[yocto] Python Error in SDK

[Erik Bolton]

Hey All;


This has been brought up before (although I think the error was different), but I'm having a lot of issues with the version of Python included with the SDK.


We use Python for code generation as part of our project. If I source the environment script and try to run our Python scripts I get this:


Traceback (most recent call last):
  File "/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/lib/python2.7/site.py", line 569, in <module>
    main()
  File "/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/lib/python2.7/site.py", line 551, in main
    known_paths = addusersitepackages(known_paths)
  File "/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/lib/python2.7/site.py", line 278, in addusersitepackages
    user_site = getusersitepackages()
  File "/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/lib/python2.7/site.py", line 253, in getusersitepackages
    user_base = getuserbase() # this will also set USER_BASE
  File "/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/lib/python2.7/site.py", line 242, in getuserbase
    from sysconfig import get_config_var
  File "/opt/poky/1.7.1/sysroots/x86_64-pokysdk-linux/usr/lib/python2.7/sysconfig.py", line 10, in <module>
    'stdlib': '{base}/'+sys.lib+'/python{py_version_short}',
AttributeError: 'module' object has no attribute 'lib'

If I try running something that doesn't exist I get this:

Fatal Python error: Py_Initialize: Unable to get the locale encoding
ImportError: No module named 'encodings'
Aborted (core dumped)

I've tried using update-alternatives to point the SDK python to my local python (Ubuntu 14.10, Python 2.7.8), but the errors persist.

I know a few people have simply deleted the python binary from the SDK, but I don't think that will help in my case.

I would try to remove it from the SDK in the actual package groups, but smartpm and a few other programs depend on it. I'm not sure they would play nice with my local version.

Any suggestions on how to fix this "correctly"?

Thanks very much.
