Hi Giovanni,
Thanks for the response.
I just checked out svn trunk and tried but it still failed.
File "/home/feng/dev/pyinstaller-svn/pyinstaller/iu.py", line 532,
in doimport
del sys.modules[fqname]
KeyError: 'bsddb'
even when I changed the iu.py: except KeyError: to except:
it still didn't work.
However, from your explanation, I made the following change:
try:
if fqname in sys.modules:
# TODO: weird, except KeyError
doesn't
# catch KeyError here
del sys.modules[fqname]
except KeyError:
and it worked. Somehow this 'except KeyError' just doesn't work here.
I did one more experiment in normal interactive shell:
>>> import bsddb
>>> del sys.modules['bsddb']
>>> del sys.modules['bsddb']
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 'bsddb'
>>> try:
... del sys.modules['bsddb']
... except KeyError:
... pass
...
>>>
So I don't know why. Maybe it's a python language bug? Or something
else special inside pyinstaller packaged binary environment
So at least, by the above change (add the if fqname in sys.modules
check), the pyinstaller works for me now.
Cheers!
Feng
