python 2.5- / 3.x - B3 does not work and shows no relevant error message

[thomasleveil]

B3 is not compatible with python 3.x and not compatible with python 2.5-

what's expected

B3 should detect that it starts from a python 3.x or <2.6 interpreter and show a user friendly error message and stop.

what's really happening

See forum topic and error 2.5

I wasn't able to test the fix. It'll need confirmation before closing the issue.

Doesn't work on Windows, please see comments to 7ede28b above for a fix

[thomasleveil]

python 3 needs to be detected even before the b3.run module is imported. see 7c63675 that does prevent B3 from starting when used with python 3.

For windows users, the drawback is that the cmd windows won't ask "press any key to continue" and they might just think B3 crashes. Anyway this is still better than having to crawl through a log and stacktrace to guess what happened.

Does anyone has python 2.5 and can run a test with it ?

[82ndab-Bravo17]

My 2.5 dll seems to have gone missing, but I changed the test to fail on 2.6 and it did, but allowed 2.7 to run. I'll see if I still have the install file for 2.5 later.

I get:

G:\b3-180b\BF3-b3-1>G:\Python25\python.exe G:\B3-180b\b3_run.py -c G:\b3-180b\BF 3-b3-1\bf3b3-1.xml Traceback (most recent call last): File "G:\B3-180b\b3_run.py", line 40, in import b3.run File "G:\B3-180b\b3init.py", line 37, in import pkg_handler File "G:\B3-180b\b3\pkg_handler.py", line 33, in from b3.functions import main_is_frozen File "G:\B3-180b\b3\functions.py", line 39, in import json ImportError: No module named json

with 2.5!!!!!

import sys if sys.version_info >= (3,): raise SystemExit("Sorry, cannot continue, B3 is not yet compatible with python version 3!") if sys.version_info < (2,6): raise SystemExit("Sorry, cannot continue, B3 is not compatible with python versions earlier than 2.6!")

in b3_run seems to work

[thomasleveil]

you mean the SystemExit exception does not stop the process ?

[82ndab-Bravo17]

No, I think that it is failing in import b3.run again, just like 3.2.2 did since json doesn't seem to be included in 2.5?

[b1naryth1ef]

If I remember correctly you can use SimpleJSON for pre-2.6.

[thomasleveil]

exact, but that would be a pity to write a bit of 2.5 compatible code just to tell the user the soft cannot be run with 2.5 :s

[b1naryth1ef]

I believe you can just replace the import. So import simplejson as json or something along those lines.
